摘要
采用现代控制理论线性二次型 (LQ)最优控制理论对飞机自动防滑刹车控制ABS系统进行了深入的分析研究 ,并利用Matlab最优控制工具箱及Simu link对刹车控制系统进行了仿真 ,仿真过程综合考虑了飞机机体、机轮轮胎、路面状况、刹车控制装置的特性 ,以状态空间表达式导出了飞机刹车滑跑的动力学模型 ,通过调节制动压力来控制机轮的滑移率 ,使其达到期望值 ,求出最优反馈矩阵 ,将反馈矩阵代入仿真模型 。
Linear-quadratic optimal control technique, Matlab optimal toolbox and Simulink were applied for aircraft anti-skid brake control system, according to the features of aircraft body, tyre, ground and brake device. The dynamic model was given by modern state-space method. The optimal state-feedback gain was calculated and the robust controller of aircraft anti-skid brake system was designed.
