摘要
文章介绍了飞机全电刹车系统的电作动机构,分析了刹车过程中的滑移率控制原理,针对滑移率变化的非线性提出了模糊PID控制方案。在滑移率偏差较大时,使用模糊控制提高系统的响应速度,在小偏差下切换入PI控制消除静差和极限环。使用模糊PID控制器,对某型飞机刹车过程的仿真表明,系统取得了很好的刹车性能。
The paper introduces the Electro - Mechanical Actuator of the aircraft electric braking system, analyses the method of braking via controlling the relative slipping ratio. Because of the nonlinear relative slip, Fuzzy - PID Algo- rithm is proposed. When the slip error is big, the Fuzzy Algorithm improves the response speed, and when the error is small, the PI Algorithm eliminates the stable error and the limit cycle. The Fuzzy PID controller is simulated on some aircraft, and the result indicates that the braking performance is perfect.
