摘要
介绍了一种由无刷直流电动机和蜗轮蜗杆机构组成的航空电动锁控制系统。采用了由电机自身所具有的转子Hall位置传感器输出脉冲信号,实现直线位置间接测量与控制,高性能AT89C51单片机作为核心控制单元,并采用硬件和软件位移限位保护,提高了系统的可靠性。实验分析表明,基于转子Hall位置传感器信号进行位置、速度双闭环控制的无刷直流电动锁控制器设计是可行的。
An aviation electric lock control system made up of brushless DC motor （BLDCM） and mechanism of worm and gear was introduced. The application of the position sensor to output the pulse signal helped realize the indirect measurement and control of linear pobition. The high performance AT89C51 micro-controller was designed as the core control unit. The adoption of the hardware and the software dual limitative position protection enhances the reliability of the linear motion system. The test shows that the method of position and speed dual-closed loop control is feasible in aviation electric lock system based on BLDCM.
