چکیده

Communication and control co-design for networked control system in optimal control in the paper. Under p – to – wσ communication sequence which sensors access communication medium and m – to – wρ communication sequence which actuators access communication medium, the plant of networked control system acts as a linear periodic time-varying system. Using lifting technology, a linear periodic time-varying system is transformed to a linear periodic time-invariant system, linear quadratic performance index of a linear periodic time-varying system is transformed to that of a linear periodic time-invariant system. An optimal state feedback control and an optimal output feedback control are given. Key-Words: communication and control co-design; networked control system; lifting technology; linear quadratic performance index; optimal state feedback control; optimal output feedback control

Modelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method

Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...

Robust Model for Networked Control System with Packet Loss

The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...

Designinga Neuro-Sliding Mode Controller for Networked Control Systems with Packet Dropout

This paper addresses control design in networked control system by considering stochastic packet dropouts in the forward path of the control loop. The packet dropouts are modelled by mutually independent stochastic variables satisfying Bernoulli binary distribution. A sliding mode controller is utilized to overcome the adverse influences of stochastic packet dropouts in networked control system...

Neural-Smith Predictor Method for Improvement of Networked Control Systems

Networked control systems (NCSs) are distributed control systems in which the nodes, including controllers, sensors, actuators, and plants are connected by a digital communication network such as the Internet. One of the most critical challenges in networked control systems is the stochastic time delay of arriving data packets in the communication network among the nodes. Using the Smith predic...
