This paper highlights state-of-the-art technologies, collectively described as Internet of Things (IoT) to improve energy efficiency in residential and commercial buildings. An appraisal of numerous studies on the subject was carried out to better understand the methods through which IoT systems are being currently deployed to improve energy efficiency in buildings, and further technological enhancements that are needed to accelerate these efficiency gains. Many of the present IoT studies have been focused on one specific problem, inefficient heating systems in buildings. Core IoT elements, such as the hardware components and management control software are usually discussed to some degree in most of the research studies. Although the types of applications varied per study, similar design patterns were observed. Some of the major design commonalities are: the choice of options for powering sensors and actuators;control methods for collecting data and controlling devices;historical data acquisition as a base to forecast ahead energy usage;and the methods by which IoT elements interact with one another. The research indicates that while similarities exist among different IoT systems, any chosen system design must be largely specific to its application. Factors such as the number of sensors used, the number of actuated devices, the optimal control method, and personal security of the end-user are application-dependent and must all be considered. Future research directions should examine optimal methods of providing remote power to devices, decipher strategies to keep isolated IoT networks secure, maintain a balance between meeting user comfort requirements and allowing a system to remain relatively autonomous, and optimize system performance in the context of the above requirements and constraints.

The relevance of the development and application of real-time systems as essential elements of ensuring the safety of complex systems is considered. The functions of its main blocks are highlighted: the network model generator, the schedule generator, and the control optimization block. Formulations of problems of existence and the construction of a valid schedule with interruptions are proposed. Unlike traditional statements, the case is considered when the graph of connections between processors is not complete and can vary over time. It also takes into account the time required to process interrupts and switches during the execution of works. A multi-product network model was built, and the necessary and sufficient conditions for the solution of the problem were indicated. New algorithms have been developed for effective planning and control of work performance, used in the design of real-time systems. An algorithm of optimal arrangement of control modules is proposed. Estimates of the complexity and accuracy of the developed algorithms are obtained. The scope of application of the developed algorithms is supposed.

Multi-robot systems are becoming widely popular in applications where a rapid response is required or where various different robotic capabilities are required. Applications such as surveillance, or search and rescue, would require an efficient team that can be deployed and optimally dispersed over the environment. This is known as the coverage control problem. The solution to this research optimization problem is affected by several external aspects, such as characteristics of the environment as well as factors that pertain to the robotic team. This work proposes a novel solution to the complete coverage problem where the team of robots is restricted with energy limitations, and must cover an environment that has time-varying regions of importance. Our results show that in a realistic scenario, where the robots have limited energy for the task in question, the proposed solution performs significantly better than a typical coverage algorithm which disregards the energy considerations of the robotic team.

In the ongoing decade, port logistics in Europe have been exposed to intense competition. Especially container ports experience competition not only for ships but also for supply chains. To adapt to this trend, terminal operators are improving the efficiency in port logistics through, among other things, automation of port operations. Most of these efforts concern processes handling shipped goods. Instead of concentrating on these well-researched improvements, we explored the feasibility and economic potential of an intelligent lighting control system. Often automating handling processes need high investments in hard- and software. This smart lighting system is supposed to control demand-actuated outdoor lights in a harbour environment. In this research, movement profiles of straddle carriers and infrastructural data were gathered and refined to build a model of the observed container terminal. The modelled infrastructure includes the position of every lighting tower and its illuminant as well as their specific power consumption and the respective area, which those lights illume. To control these lights, we developed a control algorithm. We investigated through simulation experiments the power savings for this autonomous lighting control system. Multiple influential factors of this control concept were evaluated by varying the parameterization of the algorithm. A gathered data set, containing trajectories of operating straddle carriers during full terminal utilization, is the basis for the mentioned experiments. The results of varying the utilization rate of the terminal have identified a relationship between capacity and percental power consumption, in the form of a root function. The more straddle carriers run, the less the overall power consumption is increasing. Using the intelligent light control system on full utilization saves 14.67% of the total energy. In the case of 80 % terminal utilization, 18.22 % of total energy is subject for saving effects. Besides t

This paper deals with the development of a vibration control architecture in which many stand-alone active dampers are involved. Each device is able to independently perform the control task, since it is embedded with sensors, an inertial actuator and a microcontroller, in which the control algorithm is implemented. The aim of this architecture is to improve the performance of a decentralized control strategy through a partial sharing of data between devices. The proposed control solution is based on the optimal control theory;the Linear Quadratic Regulator works with the full-state of the system, which is not available in many applications. In order to provide the entire state vector, state estimation is implemented in each device. A state recovery algorithm is adopted to improve the quality of the estimation without placing a hefty burden on the wireless channel. Numerical analysis is made in order to study the advantages of this method. Finally, the proposed solution is validated with experimental results from a clamped-clamped beam.

Tuning of fractional order proportional integral/proportional derivative controllers based on existence conditions

引用

PROCEEDINGS OF THE INSTITUTION OF MECHANICAL ENGINEERS PART I-JOURNAL OF SYSTEMS AND control ENGINEERING 2019年第4期233卷 384-391页

作者： Muresan, Cristina I. Birs, Isabela R. Ionescu, Clara M. De Keyser, Robin Univ Tehn Din Cluj Napoca Fac Automat & Calculatoare Cluj Napoca 400027 Romania Univ Ghent DySC Res Grp Dynam Syst & Control Ghent Belgium

Fractional order proportional integral and proportional derivative controllers are nowadays quite often used in research studies regarding the control of various types of processes, with several papers demonstrating their advantage over the traditional proportional integral/proportional derivative controllers. The majority of the tuning techniques for these fractional order proportional integral/fractional order proportional derivative controllers are based on three frequency-domain specifications, such as the open-loop gain crossover frequency, phase margin and the iso-damping property. The tuning parameters of the controllers are determined as the solution of a system of three nonlinear equations resulting from the performance criteria. However, as with any system of nonlinear equations, it might occur that for a certain process and with some specific performance criteria, the computed parameters of the fractional order proportional integral/fractional order proportional derivative controllers do not fall into a range of values with correct physical meaning. In this article, a study regarding this limitation, as well as the existence conditions for the fractional order proportional integral/fractional order proportional derivative parameters are presented. The method could also be extended to the more complex fractional order proportional-integral-derivative controller. The aim of this research is directed toward demonstrating that when designing fractional order proportional integral/fractional order proportional derivative controllers, the choice of the performance specifications should be done based on some specific design constraints. The article shows that given a specific process and open-loop modulus and phase specifications, the gain crossover frequency (or in general, a certain test frequency used in the design), specified as a performance specification, must be selected such that the process phase fulfills an important condition (design constraint).

The deviation from the ideal waveform causes disturbances and failure of end-user load equipment. Power traveling a long distance from the generation plant to the end-user leads to deterioration of its quality, and the intensive utilization of power leads to serious issues in the grid resulting in power quality problems. To make the system effective and able to meet modern requirements, flexible AC transmission system (FACTS) devices should be installed into the grid. The interline power flow controller (IPFC) is the latest FACTS device, which compensates for both active and reactive power among multi-line systems. The converters used in the IPFC are crucial as they can be adjusted to regulate the power flow among the lines. This paper proposes a cascaded IPFC with hysteresis and proportional resonant voltage controllers. Some main drawbacks of controllers like steady-state errors and reference tracking of converters can be easily achieved by the PR controller, which makes the system efficient and can be used for a wide range of grid applications. Hysteresis and PR controllers are explained in detail in the following sections. A comparative analysis is carried out among control algorithms to choose the suitable controller which maintains stability in the system.

Temperature control is present in many industrial processes, making this skill mandatory for the control engineers. For this reason, different training temperature platforms have been created for this purpose. However, many of these platforms are expensive, require elaborate facility accommodations, and have higher heating and cooling times, making not suitable for teaching and training. This paper presents a low-cost educational platform for temperature control training. The platform employs a Peltier module as a heating element, which has lower heating and cooling time than other thermal system implementations. A low-cost real-time thermal camera is employed as a temperature feedback sensor instead of a standard thermal sensor. The control algorithm is developed in Matlab-Simulink and employs an Arduino board as hardware in the loop to manage the Peltier module. A temperature control experiment is performed to show that the platform is suitable for teaching and training experiences not only in the classroom but for engineers in the industry.

This work is part of a research initiative that aims at increasing the overall gas turbine efficiency by means of constant volume combustion (CVC). For that purpose, flow control in the compressor becomes important, since unsteady combustion effects that may occur in a CVC are very likely to affect stability and efficiency of the compressor negatively due to flow disturbances. Active Flow control (AFC) often has to deal with uncertain flow conditions, e.g., due to turbulence, varying operating ranges, or simply environmental effects. By that, system parameters such as gain or time constants of the system model also become uncertain, making it difficult for control algorithms to ensure optimality or even stable behavior. Robust control in the sense of Ye. control tackles these problems using an uncertainty description and a nominal model of the system. In this contribution, robust control applied to a linear stator cascade is addressed when only a binary control output from solenoid valves is available. Moreover, a surrogate control variable is proposed, describing the extent of the velocity deficit. By means of a principal component analysis, this control variable is reconstructed from a single measurement input. AFC is realized via trailing edge blowing. In comparison to proportional valves, solenoid valves are cheaper and offer faster switching times with the drawback of a restricted range of the control output to integer or even binary values. Since the AI. controller, as well as most other control algorithms, results in a real-valued signal u(t) E ilk, a sum-up rounding strategy is applied to the controller output, forming a binary control output u(b)(t) is an element of {0,1}. Although it is impossible for the two outputs to completely match, unless both are integer-valued, there is proof that the difference of real-valued to binary output is bounded in its integral value. The investigations show that a switching frequency of the valves of 100 Hz is sufficient
