GA Base tuning of the PID Control of an Automatic Voltage Regulator (AVR) System

摘要

This paper addresses a robust method for optimal PID control of automatic VoltageRegulation (AVR) system to damp terminal voltage oscillation following disturbancesin power systems. The optimization is carried out by the genetic algorithmOptimization (GA) to improve their situation. The optimal tuning problem of the PIDgains to control of AVR system against parametric uncertainties is formulated as anoptimization problem according to time domain based objective function. It is carriedout under multiple operation conditions to achieve the desired level of terminal voltageregulation. The results analysis reveals that the GA based PID type AVR control systemis effective and provides good terminal voltage oscillations damping ability.
