Tuning of PID Controller Using Internal Model Control with the Filter Constant Optimized Using Bee Colony Optimization Technique

Abstract

AbstractThe present research work presents a novel control scheme for tuning PID controllers using Internal Model control with the filter time constant optimized using Bee colony Optimization technique. PID controllers are used widely in Industrial Processes. Tuning of PID controllers is accomplished using Internal Model control scheme. IMC includes tuning of filter constant λ. Compromise is made in selecting the filter constant λ since an increased value of λ results in a sluggish response whereas decreased value of filter constant leads in an aggressive action. In the present work, an attempt has been made to optimize the value of the λ by Bee colony optimization technique. Simulation results show the validity of the proposed scheme for the PID controller tuning.KeywordsInternal Model ControlPID controllerBee colony optimizationFilter constant
