Abstract

The aim of the paper is to design Fuzzy PID controller to the reduced second order system for obtaining fast raise time, quick settling time and minimal overshoot. This paper compares the performances of various tuning method for PID controller. Initially the PID controller is design by the conventional Ziegler and Nichols method and then the Fuzzy PID controller. The design of Fuzzy PID controller via reduced order model retains the original characteristics of the system. It was found that the proposed Fuzzy PID method is better than the Ziegler and Nichol’s method. An algebraic approach for model order reduction could be applied to the any higher order system for reducing the computational complexity of mathematical models in numeric simulations.
