In recent years, as Cloud Computing and Internet of Things (IoT) technologies develop rapidly, smart home technology has entered a new stage: smart electric power usage, which will break the traditional extensive management situation for electric power loads, particularly under the background of an energy crisis. People will gradually gravitate towards the demands for more energy-related and intelligent services in smart home systems such as energy saving, improved understanding of electrical consumption and electrical safety of appliances. When the power consumption is considered by a smart grid, detailed electrical information of power loads will be perceived for demand management and optimization. To address these issues, measuring and monitoring the power of residential individual appliances are highly demanded by many applications.

Computer aided control in biomedical applications is gaining more and more popularity due to numerous research studies that have proven the efficiency of automatic control over manual dosing, which is highly susceptible to human errors. Optimal drug dosing is best achieved using automatic control, which triggers important benefits in terms of both costs and patient side-effects. However, mathematical models for patients are highly susceptible to large modeling uncertainty. A predictive control algorithm is designed in this paper for optimal multidrug control of hemodynamic variables. Improved closed loop performance is obtained compared to similar control strategies, for ± 30% modeling uncertainty. The simulation results demonstrate that predictive control is a feasible solution for optimal drug dosing. An analysis of the closed loop performance for significant patient variability shows that controllers tuned using a nominal patient model often fail to achieve desired robustness. To limit the effect of modeling uncertainty, the prediction model should be updated using an online identification tool to extract patient features. © 2024 AACC.

The published results of previous researches of functionally stable systems are generalized based on the theory of recovery control. The verified structural scheme of the mathematical model for solving the problems of recovery control of functionally stable systems by the method of inverse dynamics problems is used. For a direct functionally stable system, it is possible to directly observe the parameters of the system and, therefore, there is no need to identify the object. In the adaptation circuit, it is necessary to have only an adjustment algorithm that adjusts the parameters of the recovery device in accordance with the obtained observation results. On the basis of the analysis of the features of optimal direct functionally stable systems, a generalized optimality condition is proposed using the theory of recovery control. The structural scheme of the optimal direct adaptive system is substantiated. The study outcomes show that the presence of delays in the object leads to the need to evaluate the additional parameters that are not directly involved in the adjustment of the control device, i.e., the delay causes complications in the adjustment algorithm. The conducted investigations have allowed the formulation of conditions for optimal algorithms of adjustment of direct adaptive systems. The structural scheme of the optimal direct adaptive system is also obtained. In further research, based on the analysis of the structure of predictors and their features, the conditions are imposed to ensure their optimal structure. Consideration of this issue will also allow us to consider in detail the class of optimal indirect functionally stable systems. © 2022 IEEE.

The article presents the results of studies that allowed us to establish that in order to ensure stable operation of the multiple insert tools on CNC machines in a given time interval, it is necessary to control the cutting properties of replaceable multi-sided carbide inserts. The paper suggests a method for determining the cutting properties of the carbide multiple insert tools and the physical and mechanical properties of the material using of the thermal EMF value generated by a natural thermocouple, composed of the tool material and the material to be processed. The physical validation of the thermal EMF signal analog-to-digital conversion use for the state of carbide inserts evaluation in the set of built-up tool is given. Fast-flowing contact processes in the intermittent cutting conditions are analyzed. A relationship between the thermal EMF value of the trial run and the energy coefficient in the permissible cutting speed formula is established. Experimental research on intelligent production machine showed the effectiveness of the suggested method. © 2018 IEEE.

The article is devoted to the development of a generalized formalized approach to the choice of a cutting tool at the stage of pre-production engineering. The relevance of the study, aiming at increasing the efficiency of acquisition of the tooling system for machine tool equipment with CNC, is substantiated. The shortcomings of the heuristic method (most frequently used during the equipment and tools selection) are indicated, the ways of solving this problem are shown. The application limitations of the developed approach are shown, the application of the qualimetric approach is justified. The work uses the theory of sets, mathematical programming, elements of the decision-making theory. An algorithm for multicriteria selection of a cutting tool is developed, and software based on it, which provides the technologist with a ranked list of tools that are optimal for a given process. It is supposed that the developed method can be integrated into existing CALS-systems at manufacturing enterprises. © 2018 IEEE.

Wind energy is one of the widely applied renewable energies in the world. Wind turbine as the main wind energy converter at present has very complex technical system containing a huge number of components,actuators and sensors. However, despite of the hardware redundancy, sensor faults have often affected the wind turbine normal operation and thus caused energy generation loss. In this paper, aiming at the wind turbine hydraulic pitch system, data-driven design of process monitoring(PM) and diagnosis has been realized in the wind turbine benchmark. Fault tolerant control(FTC) strategies focused on sensor faults have also been presented here, where with the implementation of soft sensor the sensor fault can be handled and the performance of the system is improved. The performance of this method is demonstrated with the wind turbine benchmark provided by Math Works.

The problem of constructing a mathematical model for calculating the stationary characteristics of the gas in the pipeline is solved. An analysis of models that are most frequently used in practical guidelines and regulatory documents on the operation and calculation of gas pipelines was carried out. It is shown that the disadvantages of known models are caused by the desire to obtain distribution of pressure and gas temperature in the form of obvious analytical expressions that are not connected between themselves. It has been established that such expressions can only be obtained as a result of the assumptions about the constancy of the Joule-Thomson coefficient along the line, as well as an exception from the consideration of the change in the kinetic energy of gas, the loss of pressure on overcoming the force of gravity and loss of pressure to change the amount of movement. Moreover, in a number of well-known models, it is necessary to impose an assumption about the linear distribution of pressure, and the concept of average temperature, i.e. unchanged temperature along the line, is used. In order to eliminate the listed disadvantages, a gas characteristics distribution model containing a system of three integral equations corresponding to the laws of energy conservation, mass and the amount of gas flow movement are proposed. For the resulting model, a simple difference scheme of the joint solution of the specified system of equations was constructed. The results of a numerical verification confirming the adequacy of the proposed model are given. © 2021 IEEE.

In the operating rooms and the intensive care unit, it is crucial to manage the patient's hemodynamic status, which includes factors like cardiac output and mean arterial pressure. Anesthesiologists confront a difficult task while monitoring high-risk patients. Cardiac output optimization has been found to enhance the result of high-risk patients in terms of hospital stay, mortality rate, post-operative problems, etc. The application of standard control approaches is restricted because the mean arterial pressure response of a patient using vasoactive medicines is modeled by a first-order dynamical system with time-varying parameters and a time-varying delay in the control input. In order to circumvent implementation challenges, this work develops an approximation technique that describes the system using a higher-order model. Predictive control is therefore used to comprehend the practical application of higher-order hemodynamic systems. The effectiveness of this strategy is demonstrated by the simulations and outcomes that are given. © 2023 IEEE.

In this paper we focus on the target capturing problem for a swarm of agents modelled as double integrators in any finite space *** agent knows the relative position of the target and has only an estimation of its velocity and *** that the estimation errors are bounded by some known values,it is possible to design a control law that ensures that agents enter a user-defined ellipsoidal ring around the moving *** know the relative position of the other members whose distance is smaller than a common detection ***,in the case of no uncertainty about target data and homogeneous agents,we show how the swarm can reach a static configuration around the moving *** simulations are reported to show the effectiveness of the proposed strategy.
