Salp swarm algorithm (SSA) is a relatively new bio-inspired meta-heuristic optimization algorithm that mimics the navigating and foraging behavior of salps in oceans. This paper presents an orthogonal quasi-opposition-based learning-driven dynamic SSA (OBDSSA) for solving global optimization problems. The proposed methodology integrates orthogonal quasi-opposition-based learning (OQOBL) tactic and dynamic learning (DL) strategy with SSA to improve its performance. The OQOBL technique is used to enrich the exploration and development capability of the canonical SSA to help the salp chain jump out of local optimum, while the DL mechanism is applied to the basic approach to expand the neighborhood searching capabilities of the search agents. To investigate the proposed operators and OBDSSA algorithm, 18 widely used benchmark functions and parameter extraction problem of photovoltaic (PV) model have been experimented upon. The comparisons reveal that OBDSSA outperforms all competitors, including the standard SSA, SSA variants, and other state-of-the-art algorithms. Finally, the developed approach is applied to path planning and obstacle avoidance (PPOA) tasks in autonomous mobile robots (AMR) and satisfactory results are obtained.

This study summarises the implementation of software system architecture and relevant modules to enable cooperative adaptive cruise control (CACC) functionalities as an extension of adaptive cruise control (ACC), thereby leveraging the lessons learned from prototype ACC vehicle testing as well as ideas from prior research. These activities were conducted in the United States under a cooperative agreement between the Crash Avoidance Metrics Partners, LLC and the Federal Highway Administration. A key outcome of this project was to understand the implementation of advanced capabilities for the CACC algorithm in a very structured manner. With the introduction of each CACC module, the impacts on the behaviours of vehicles following in a string (or string stability) were quantified to establish potential performance enhancements to automated following systems.

DESIGN ALGORITHMS FOR DIGITAL-control SYSTEMS WITH DEADBEAT UNIT STEP RESPONSE

引用

IEE PROCEEDINGS-D control THEORY AND APPLICATIONS 1983年第3期130卷 119-127页

作者： SHIH, FY Department of Electrical Engineering Chung Cheng Institute of Technology Ta-Hsi Republic of China

A model is developed for digital control systems with deadbeat unit step response. Deadbeat systems with state feedback and state compensation configurations are synthesised based on the developed model. For plants with inaccessible states, a linear state transformation technique is introduced to obtain deadbeat output compensation design. The state feedback law presented in this paper for a deadbeat controller can be combined with the pole placement technique for a deadbeat observer to solve the observer-controller problems. A practical study that compares various designs is made from the point of view of parameter sensitivity.

AUTOMATIC controlS IN BUILDING SERVICES

IEE PROCEEDINGS-B ELECTRIC POWER APPLICATIONS 1988年第3期135卷 105-133页

作者： HARROLD, MV LUSH, DM Arup Research & Development London UK

Until recently, the term “controls” was confined, in building services, to the thermostatic devices associated with the heating, ventilating and air conditioning (HVAC) systems. Nowadays, the definition is generally considered as encompassing the motor starter and control panels, energy management and building automation systems, lighting controls and, at least, the interfacing with fire, security and lift systems. Based on this premise, the review covers the range and applications of the automatic control systems now available, with a review of the state of the art, and some predictions as to the likely direction in future. The aim of the review is to provide an insight into current and future control systems. The intention is to enable electrical engineers to better co-ordinate their activities with their mechanical and HVAC colleagues who commonly specify the control systems which have to be integrated into the total services design. The topics reviewed include the effect of correct selection on the operation of the HVAC system, the electrical requirements of controls, guidelines on the application of controls to particular systems, coordination of effort between all the parties involved, the variations and scope of EMS/BAS and direct digital control, lighting control, and testing and commissioning.

Artificial neural network for modelling of the correlation between lateral acceleration and head movement in a motion sickness study

引用

IET INTELLIGENT TRANSPORT SYSTEMS 2019年第2期13卷 340-346页

Motion sickness (MS) usually occurs when travelling in a moving vehicle, and especially experienced by the passengers compared to the driver. The difference in their head movements with respect to the direction of lateral acceleration affects the MS severity level. When experiencing curvature, the passengers normally tilt their head in the same direction as the lateral acceleration, while the driver tilts his/her head against it. This study proposes a correlation model between the lateral acceleration of the vehicle and the head movements of the driver and a passenger via an artificial neural network. Experimental datasets were used in the modelling process. The influence of the number of hidden neurons with respect to the model accuracy has also been investigated. Then, the correlation from the model was expressed as a mathematical equation. This mathematical representation model can be beneficial in the design of vehicle motion control systems in order to mitigate the MS effect.

Modelling of real-time constraints using SOL for embedded systems design

The use of SDL has arisen as a promising way of dealing with the increasing complexity of embedded real-time systems. However, SDL does not take into account non-functional aspects, such as the time requirements, that are especially important in the context of real-time systems. Furthermore, the associated code generators do not integrate the management of temporal constraints. A real-time semantic extension to SDL for real-time systems modelling is proposed. The real time profile is added to SDL in order to prepare the real-time code generation. To illustrate the proposal, an example of a speed regulator is presented.

Sliding mode learning based congestion control for DiffServ networks

In this study, a robust sliding mode learning control scheme is proposed to address the congestion control problem in differentiated services (DiffServ) networks. A validated non-linear network model is based on fluid flow theory corresponding to two important services, namely, the premium traffic and the ordinary traffic. The proposed congestion controller is able to efficiently cope with both the physical network resource constraints and unknown time delays associated with networking systems. Numerical results are presented to illustrate the effectiveness of the proposed control scheme.

The road to plant validation

引用

computing & control engineering JOURNAL 2001年第4期12卷 169-178页

作者： Clarke, D Univ Oxford Invensys Univ Technol Ctr Adv Instrumentat Oxford England

Effective production requires serviceable unit processes, under stable control with credible sensed data and precise actuation. Validation of these components is not just an aid to safe operation, but can also enhance the availability of the plant. Cost-effective validation uses standard metrics for the intercommunication of results via a network and starts at the sensor and actuator level. In particular, greater availability comes from limp-home features that provide a degree of operability even in the presence of faults. This can be achieved at the device level, by adjusting a loop's PID regulator, by using auxiliary variables and data-fusion, or by the reconfiguration of a model-predictive controller (MPC). Examples are given of self-validating (SEVA) field instruments and the effect of adjusting a control loop using SEVA data. Plant validation is a combination of SEVA devices and of change detection based on the residuals derived from an MPC model.
