AC servo motor speed and position control using Particle Swarm Optimization PSO

Abstract

I n this article, a new design method, called Particle Swarm Optimization PSO , is used for the determination of PID control parameters; this is designated for the controlling of the speed and the position of the AC servomotor. For the determination of the decision parameters AC servomotors are mathematically modelled. Rise time, settling time, and overshoot are taken into consideration, during the optimization process. Controller’s performance is determined based on different criteria, such as, ITAE Integral of Time Weighted Absolute Error , IAE Integral of Absolute Error , ISE Integral of Squared Error and ITSE Integral of Time Weighted Squared Error . Superiority and accuracy of the proposed technique was verified by simulation results. In addition, considering the quality of the obtained results, proposed technique is found effective and strong in reduction of the error of motion control systems
