Design of Electronic PID Controller Using Genetic Algorithms

Abstract

This paper presents a Genetic Algorithm (GA)-based electronic Proportional-Integral-Derivative (PID)Controller tuner. The tuning is based upon themaximization of a comprehensive fitness functionconstructed as the inverse of Peak Overshoot (Mp). Thisapproach has a some advantages, it gives a clearer andsimpler representation of the problem, simplifieschromosome construction, and totally avoids using binaryencoding and decoding so as to simplify softwareprogramming.This paper addresses to demonstrate the capabilityof GA's to solve complex and constraint optimizationProblems via utilizing GA's as a general-purposeoptimizing tool to solve different Control system designproblems.
