摘　　要：通过综合运用模糊PID控制算法、空间电压矢量脉宽调制方法(SVPWM)与矢量转换技术,搭建了一种包括速度闭环与电流矢量闭环的二相混合步进电机双闭环的控制系统,并借助于MATLAB/Simulink强大的建模仿真功能,对步进电机双闭环控制系统进行了仿真分析。相关仿真结果表明,该控制系统具有较好的控制性能与动态响应能力。A control system of double closed-loop for two-phase hybrid stepper motor which including speed closed-loop and current closed-loop is established based on fuzzy-PID control algorithm, space vector pulse width modulation （SVPWM） method and space vector conversion, and the performance of the doubled closed-loop control system of stepper motor is analyzed by the powerful modelling and simulation function of MATLAB/Simulink. The simulation results show that the control system has favorable control performance and dynamics characteristic.
