Decentralized PID Controllers for Unstable Systems

Part of the Advances in Industrial Control book series (AIC)


The chapter deals with the design of the decentralised PID controllers for the unstable system. The method focuses on incorporating the higher-order harmonics in evaluating the ultimate gain of the process. It is observed that the higher-order harmonic have significant affect on the system performance and the incorporation of the same improves the performance tremendously.
