摘要
设计的飞机全电刹车系统,以四无刷直流电机驱动四滚珠丝杠布局的机电作动机架,取代了原来液压刹车的活塞阀门作动机架,电机通过传动装置驱动滚珠丝杠松刹刹车盘实现飞机的刹车。在硬件设计上,刹车控制器的CPU采用TI公司的电机及运动控制专用DSP2407,以满足对控制系统的性能要求;4台无刷直流电机的换相信号由可编程逻辑器件完成;对电机的驱动采用了MOSFET与栅极驱动芯片IR2130组成的功率驱动电路,实现了无刷直流电机的高效驱动。
The structure and aircraft electric braking system was presented. The piston and valve actuated housing for hydraulic braking system was replaced by electro-mechanical actuated housing, which consisted of four motors and four ball screws. The ball screw, driven by the motor through gearing, put pressure to braking carbon stack. The CPU of digital controller used DSP TMS320F2407, which was designed for motor and motion control applications. The control signal for brushless DC motor was produced by programmable logic device. The motor driving circuit comprised by MOSFET IR2130 was used to drive the motor efficiently.
