Performance Analysis of PMSM Drive Using Ant Colony Optimization

This paper proposes an optimization algorithm to control the transient speed response of a permanent magnet synchronous motor (PMSM). The transient response of motor under starting, speed reversal, as well as during load disturbance conditions has been considered. The aim is to minimize maximum overshoot, rise time, settling time, peak time and integral absolute control error of the PMSM shaft speed, with the aid of a PID speed controller, so as to achieve fast and efficient transient speed response. Ant Colony Optimization (ACO) technique has been employed for determining the gain coefficients (proportional, integral and derivative) of the PID speed controller. The results demonstrate that with the use of ACO technique improved dynamic performance of PMSM drive can be achieved in comparison to the classical Ziegler-Nichols method of PID tuning under different operating conditions.
