This paper studies the problem of designing robust Hinfin controllers for networked control systems (NCSs) with both network-induced time delay and packet dropout by using active varying sampling period method, where the sampling period switches in a finite set. An active varying sampling period method using both clock-driven and event-driven sensor is proposed, then by modeling the system with varying...
In this paper, model output following control based on command generator tracker is designed and applied to networked aluminum plate thermal process. One of the most important problems on networked system is the time delay problem. An explorative technique is that time delay is approximated as high order rational transfer functions. Therefore, the approximated high order system must be analyzed. Model...
Based on the controlled process that is linear time-invariant system, the network-induced long time delay is viewed as time-varying parameter uncertainties. The uncertainty parameters model of networked control systems with long time delay is set up. The existing conditions of asymptotic stability for networked control system with long time delay are presented by Lyapunov method and robust control...
Implementing a control system over a communication network induces inevitable time delays and packet dropout that degrade performance and can even cause instability. In this paper, adjustable deadbands are explored as a solution to reduce network traffic in networked control system and we presented a new modeling method for networked control system with random time delays and communication constraints...
This paper develops an optimal robust control algorithm for finding digital computer control of decentralized stochastic singularly-perturbed large-scale actuator type systems with multiple time varying delays. Due to the derived algorithm concerns at each moment, the found controller is also suitable in the time varying condition. Moreover, this system possesses the fast response characteristics...
