Abstract:

This paper presented a robust PID controller design for time delay system. This controller will be utilizing the gain-phase margin method; a specification-oriented parameter region in the parameter plane that characterizes all admissible controller coefficients sets can be obtained. Tuning of a PID controller refers to the tuning of its various parameters (P, I and D) to achieve an optimized value of the desired response. The basic requirements of the output will be the stability, desired rise time, peak time and overshoot. A compromise between the performances of the system with Ziegler-Nichols method is also included. Here we are measuring the plant response with and without delay condition with respect to original reference signal. Small modeling error is encountered and it is gradually detuned to a PID controller.
