Abstract： Aiming at the inherent drawbacks of the hybrid stepper motor，the distortion of the mathematical reference model and the electromagnetic loss caused by hysteresis and eddy of the HSM，the optimal performance index，direct current feedback（DCF）and the model of self-correction in the limited time was pulled into the HSM controlled system based on the structure of the HSM，the theory of stepper motor subdivision control，the optimal control and the adaptive control. The general subdivision control and optimized subdivision control was used in the Simulink simulation based on the mathematic model of three-phase HSM respectively. The results indicate that the HSM controlled system has better performance using optimized subdivision control.
