无人机电控刹车阀指令响应测试系统设计

Test System Design of Responding to Control Instructions for UAV Electric Brake Valve

为测试无人机电控刹车阀指令响应性能,定位其输出的刹车压力与期望值间差异来源,设计了一套测试系统。根据机载应用场景搭建了硬件测试环境,开发了控制程序和相关模型。通过计算并比较刹车压力的期望值、反馈值及输出值,最终实现定位误差来源。选取两套电控刹车阀进行试验,结果表明,设计的测试系统运行稳定,准确给出了被测电控刹车阀的指令响应性能,快速定位了刹车压力误差来源。提高了无人机刹车系统排故效率,具有应用推广价值。

A test system is designed to test the performance of UAV（unmanned aerial vehicle） electronic-control brake valve instruction response,and locate the source of difference between its output brake pressure and expected values.According to airborne application scenarios,hardware test environment is built,control software and correlation model are developed.By calculating and comparing expected value,feedback value and output value of the brake pressure,the source of difference is located.Two sets of electronic-control brake valve are chosen and tested,the results show that the designed test system runs steadily,which provides the instruct response performance of the electronic-control brake valve correctly,and locates the source of brake pressure error quickly.It improves the efficiency of troubleshooting in UAV brake system,and has a value of application and promotion.
