介绍了直流无刷电机的转速、电流双闭环直流调速系统的组成及数学模型，通过对该系统的动态特性和静态特性的分析得出，双闭环直流调速系统避免了在单环系统中存在的两种反馈牵制的缺陷，可以获得了良好的静、动态品质。同时，运用了Matlab软件对采用正弦脉冲宽度调制的直流无刷电机系统进行建模与仿真，观测双闭环系统稳态与动态以及有关控制参数变化的影响。最后，仿真结果证明采用正弦脉冲宽度调制技术对双闭环直流调速系统控制的有效性。

This paper introduces the composition of double closed loop DC speed control system of DC motor speed and cur-rent, it is described the working principle of DC PWM converter and the calculating method of the pulse width modulation technolo-gy. Using the Matlab software to the induction motor system of modeling and simulation based on the technology of SPWM. Obser-vation on the steady state and dynamic system using SPWM control mode and the influence of control parameters. Finally, experi-mental results show that the SPWM technology for effective control of double closed loop DC speed control system.
