| 摘 要： | 针对包含非线性和不确定性的飞机防滑刹车控制系统,本文提出了一种基于LuGre摩擦模型的滑模变结构控制器的设计方法.通过分析系统模型,离线构建了在不同速度和路面参数条件下系统的最优滑移率控制表,同时使用基于动态模型的观测器技术对轮胎/路面不确定的结合性能进行在线辨识.并利用指数趋近率的滑模变结构控制方法有效地抑制了系统的抖振.

| Abstract: | The author proposed a design method of sliding model controller which based on the LuGre friction model for the aircraft anti-skid brake system,which contains nonlinearity and uncertainty.By analyzing the model,it constructed an optimal slipping ratio control table at different speeds and road conditions off-line.It identified the tire/road parameters on-line by using dynamic model based on the observation technology.An exponential approach law of variable structure control with sliding mode method was prop... |
