Second Generation Of PID Controllers For Reference In Put Tracking

Abstract

The paper presents the birth of the second generation of PID controllers for possible replacement of the first generation of PID controllers. It presents the dynamics of the control system incorporating one of the controllers: PID, I-PD, PD-PI and PI-PD and a highly oscillating second order-like process. The controllers are tuned and compared with a conventional tuned PID controller. The performance is judged through the maximum percentage overshoot, maximum percentage undershoot and these ttling time characteristics of the time response of the control system to a unit step reference input.
