A robust speed controller which is designed by employing fuzzy logic control and particle swarm optimization (PSO) is presented for a permanent magnet synchronous motor (PMSM) drive system. The prime problem of fuzzy PI controller is the design of fuzzy rules with expert experience. The performances of fuzzy PI controller are degraded because of expert experience. In order to solute default of conventional fuzzy PI controller, the PSO is used to optimize the parameters of membership functions of fuzzy logic controller to automatically acquire the fuzzy space structure of system Simulation results show that the proposed approach gives a better dynamic speed response and is robust to external load disturbance.
