The design of adaptive fuzzy PID controller with Smith compensator for Network Control Systems

Abstract

Due to the problems in the Network Control Systems, such as data packet loss, communication delay, network interference, signal jamming. It's hard to achieve a good result when using the conventional control algorithm. In this paper, aiming at the existing problems of Network Control Systems, a new kind of controller is designed which combined with Smith estimated compensator with the buffer and the adaptive fuzzy PID controller. We use TrueTime toolbox to test this controller, the results show that the designed controller used in this paper can increase the adaptability of the system and obtain a better control effect.
