However, these motors have a nonlinear characteristic arisen from motor dynamics and load characteristics. To overcome this problem, a new speed controller based on particle swarm optimisation for the drive system is proposed in this study. To illustrate the performance of the proposed controller, a conventional proportional integral controller is used too to the speed control of permanent magnet synchronous motors. Simulations are realized by the proposed strategy and the results are compared with the conventional control.
