A novel auto-tuning robust PID controller for networked control system

Abstract

Network-induced delay has a significant effect on the performance of NCS. The existence of network makes the design and analysis of NCS complex. This paper aims to present a novel dual PID controller for NCS after making some reasonable simplification of the complex structure of NCS. One of advantages of the novel PID controller is that it improves dynamic performance and disturbance rejection capability. Meanwhile, the control performance of the novel PID has been compared with that of a conventional PID.
