The invention discloses a fuzzy hysteresis current control system and method for a permanent magnet synchronous motor. Speed error and error variation are taken as inputs of a fuzzy logic controller,an output G is matched with an output signal of the hysteresis controller, PWM (pulse width modulation) is controlled to generate six-channel PWM signals with corresponding duty cycles, and six powerswitching tubes of an inverter are controlled to enable the motor to run stably. Compared with the traditional method, the response speed and steady-state precision of current tracking control are better.
