摘要
针对飞机防滑刹车系统的复杂性和非线性,在分析滑移率控制式飞机防滑刹车系统的工作原理基础上,提出了一种基于无模型自适应控制的飞机防滑刹车控制算法;该算法无需精确的动力学模型,直接利用输入输出信息实现飞机防滑刹车的最佳滑移率控制;仿真结果表明:采用无模自适应防滑刹车控制算法,在5s之内就能获得稳定的滑移率,为提高飞机刹车的效率提供了一条新的思路。
Considering the complexity and nonlinear of aircraft antiskid braking system, by analyzing the principle of aircraft anti--skid braking system, an aircraft anti--skid brake control algorithm based on model free adaptive control is presented. Not need to establish accurate dynamic model, the method can achieve optimal slip ratio control by using the information of braking system input and output. Simula- tion results show that the control scheme based on model free adaptive control achieve stable slip rate within five seconds, and provides a new way of improving the efficiency of the aircraft brake.
