Genetic Algorithm-based Precision Tuning of Digital P-I-D Controller for Second-Order Systems

Abstract

Tuning of the PID controller is often done by trial and error which is tedious, · time consuming and relatively inefficient. A more reliable and etricient approach of tuning the PID controller using genetic algorithm is presented. The scope of this work is limited to obtaining control parameters of a digital PID controller for a second-order system, given the desired time-response parameters.
