Time-Delay Compensation And Controller Design Of Networked Control Systems

With the development of computer technology, some considerable attentions have been directed to the integrated control systems and network communication control system. So Network Control System(NCS) is proposed. In this thesis ,the paper introduces the engineering background and research achievements, and focuses on the progress of network delay. The causes and the characteristic of network-induced delay are analyzed. According to the different of sampling time and drive way, model is built and analyzed. Depending on the different models, the controller with the compensation about the fixed time delay and random delay controller are designed. This paper focuses on using Fuzzy - PID controller against uncertainty delay to design and simulation testing. In conclusion,Simulink toolbox,named by Truetime,based on Matlab has been introduced in this paper. And the characteristics of the NCS simulation results are given.
