对机载雷达用无刷直流电动机位置、转速、电流闭环驱动控制系统进行了仿真分析，并利用仿真结果来指导实际系统的设计。设计了无刷直流电动机PWM控制器、角位置与速度检测等硬件电路以及位置、转速、电流闭环控制系统。通过硬件和软件的合理设计，使系统获得较好的动、静态性能。

The position and speed-current close-loop control system for brushless DC motor used in airborne radar is simulated and analyzed in this paper, and a real system can be designed under the guidance of the simulation results. PWM controller, angle position and speed detection circuits, the position and speed-current close-loop control system for brushless DC motor are designed. We can achieve good dynamic and static system performance with a rational design of hard-ware and software.
