| 摘 要： | 飞机防滑刹车控制的关键是控制机轮的滑移率，为了使机轮工作在最佳滑移率，得到最大结合系数，提出了一种基于滑移率控制的防滑刹车变结构控制律。由于飞机滑跑时的真实速度很难测量，为此采用广义卡尔曼滤波器得到飞机刊车系统非线性模型的状态估计，状态估计值作为防滑刹车控制器的输入。计算机仿真结果显示该控制律改善了飞机的防滑刹车性能，具有较强的鲁棒性。

| Abstract: | The key of aircraft anti-skid braking control is to control the tyre slip ratio. For the sake of the tyre works under optimal slip ratio, a braking variable structure control (VSC) law based on slip ratio control was introduced so as to obtain the maximum friction coefficient. The aircraft velocity is difficult to be measured, therefore using generalized Kalman filter to estimate the state of nonlinear model, which is the input of anti-skid braking controller. Computer simulation shows the aircraft braking performance is improved and the braking system has a strong robust characteristics. |
