Abstract :
The current control is used in many fields especially in AC motor control because the current control loop is the inner loop of the three-closed-loop structure. Aiming at the simple and robust current control technique-HCC (hysteresis current control), the paper introduces the principle. Based on the literature, simulation model of HCC applied in AC motor vector control is given. The relationship of phase current error and tolerance band, and factors that effect HCC performance are analyzed. The simulation results are consistent with the theoretical analysis.
