| Abstract |
In this paper we present a new PID controller design method using IMC design. The PID controller is derived based on the {infty}-norm of sensitivity function to guarantee stability and performance robustness. This new PID controller is suitable for the plant with right half plane zeros or with time delay. The Simulation results show that the new method is superior to Ziegler-Nichols, Morari-Zafiriou, Mattezzoni-Rocco methods in respects in overshoot and settling time. |
