Fuzzy Immune Control Based Smith Predictor for Networked Control Systems

Haitao Zhang and Zhen Li

Abstract—According to the fact that network is a class of discrete event system. Discrete-event simulation tool Sim Events is used to build network dynamic model so as to simulate network-induced delay and packet dropout in networked control systems. The concept of round trip time is introduced to estimate network-induced delay, which is compensated by Smith compensator. By using the control algorithm composed of immune feedback control and PI control, we achieved the goal of overcoming control deviation caused by changes of object model. The simulation results illustrate that the fuzzy immune PI control based Smith predictor provides better performance.

Index Terms—networked control systems, Sim Events, Smith compensator, fuzzy immune PI control
