This paper proposes a fuzzy PI hybrid speed controller for a PMSLM (Permanent Magnet Synchronous Linear Motor), which is based on a friction disturbance observer. It can improve the problems caused by the friction disturbance and the system parameters perturbation. Also the problem of the blind area for fuzzy control is eventually eliminated, because of the introduction of the PI control. Finally, through the simulation test and comparative analysis with the traditional PID control method, the validity and rationality of the control scheme is illustrated.
