Optimal multirate control of the networked control systems is investigated in this paper. Under p – to – wσ communication sequence that sensors access communication medium and m – to – wρ communication sequence that 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 ...

Functionality and performance of modern machines are directly affected by the implementation of real-time control systems. Especially in networked teleoperation applications, force feedback control and networked control are two of the most important factors, which determine the performance of the whole system. In force feedback control, generally it is necessary but difficult and expensive to a...

In this paper, fault detection of networked control systems with random delays, packet dropout and noises is studied. The filter is designed using a minimum error entropy criterion. The residual generated by the filter is then evaluated to detect faults in networked control systems. An illustrative networked control system is used to verify the effectiveness of the proposed approach.

Networked control system is a new research hot-point. To solve the control problem of distributed industry environment with large scale and real time requirement, the networked system wherein the control loops were closed through a real-time network was proposed. A new model for a kind of networked control system was presented. For reason of the model uncertainty, a design method and simulation...

The rapid explosion of information technologies in recent years has contributed to a substantive change in the social dimensions of information-sharing, and is forcing us to revise substantially our old assumptions regarding the knowledge/power dynamic. In this article, we discuss a range of strategic information-management options available to individuals and institutions in the networked soci...

To deal with random delays in Networked Control System (NCS), Modified Fuzzy PID Controller is introduced in this paper to implement real-time control adaptively. Via adjusting the control signal dynamically, the system performance is improved. In this paper, the design process and the ultimate simulation results are represented. Finally, examples and corresponding comparisons prove the signifi...

In the recent years the usage of data networks has been increased due to its cost effective and flexible applications. A shared data network can effectively reduce complicated wiring connections, installation and maintenance for connecting a complex control system with various sensors, actuators, and controllers as a networked control system. For the time-sensitive application with networked co...

ABSTRACT In this paper, the modeling and performance analysis of Networked Control System (NCS) subject to random delays and packet losses are discussed. Stochastic control theory is used for handling the random time delay and packet losses. Stochastic optimal strategy for networked control system (NCS) is obtained with random delays and packet losses when the system matrices are known. A new s...
