Performance Analysis of Controllers For AGC And AVR in Two Area System

Abstract

This paper presents performance analysis of different type of conventional and intelligent controllers for AGC and AVR system. The purpose of AGC controller is used to  maintain zero steady state error in frequency deviation. The role of AVR is to hold terminal  voltage magnitude  of  the generator  at  a preset value. In  this  paper,  simulation  of  AGC  and AVR has been carried out  using PID,  IMC ,  FLC  and  FLC-IMC in MATLAB environment and the simulation results have been presented. Also, a comparative analysis of different conventional and intelligent controllers has been done. The designed controller effectively  reduces the  frequency  deviation and  regulates  terminal voltage of synchronous  generator  to  a desired value.
