【Abstract】 This paper analyzes the working principle of the permanent magnet linear synchronous motor， builds mathematical model based on the current space vector. A self-tuning fuzzy control strategy is put forward and applied to vector control system for the permanent magnet linear synchronous motor. The simulation results show that the vector coordinate transformation theory combined with the control strategy of fuzzy controller can realize motor tracking control in the whole trip， speed curve can faster achieve stability， control effect is more ideal.
