Simulation of PSO-PI controller of DC motor in Micro-EDM System for biomedical application

Abstract

An Electrical Discharge Machining is one off the non-traditional machining processes. It is now b been used widely in many applications due to its ability to machine maaterials with good surface finish. This paper presenteed a new Micro-Electrical Discharge Machining controller model using Particle Swarm Optimization algorithm for efficient ssearch and optimization of Proportional-Integral controller parameters in order to achieve a better positioning system especially in biomedical application. This control method was simula ated using MATLAB/SIMULINK to control DC moto or. From the simulation, it was found that the proposed method gives be etter performance with improved step response for pre ecise positioning system in micro-EDM as the settling time and overshoo ot are reduced.^p
