CMAC-PID控制在飞机防滑刹车中的应用

提出了一种基于CMAC神经网络与PID相结合的控制方法,利用传统的PID控制器实现反馈控制,保证系统的稳定性并抑制扰动;利用CMAC神经网络控制器实现前馈控制,保证系统的控制精度和响应速度。以某型飞机为例,针对不同的跑道(干、湿、冰)情况,将该方法和传统的PID控制方法在MATLAB环境下进行了数字仿真。仿真结果表明:基于CMAC-PID控制方法较传统的PID控制方法,可以大大地提高飞机防滑刹车效率,具有更好的刹车控制效果,并具有较强的鲁棒性,为飞机防滑刹车系统的控制提供一条新的思路。

Research on Aircraft Anti-Skid Braking Based on CMAC-PID Control

A new method based on CMAC and PID control was proposed. The traditional PID controller that realizes feedback control, not only guarantees the stability, but also restrains the disturbance. The CMAC controller realizes feed forward control and guarantees the control precision and response speed. Taking a type of aircraft for example, with different runway condition （dry/wet/ice）, the computer numeral simulation with MATLAB was established. Compared the control performance of traditional PID control with PID control based on CMAC, the result showed that PID control with CMAC method could achieve a more ideal control effect and had a stronger robust characteristic than traditional PID control, and the braking efficiency had been improved greatly by controlling wheel slid-ration. It provided a new way for controlling aircraft anti-skid braking system.
