摘要
飞机着陆自动跟踪控制系统,采用微分几何反馈线性化处理非线性方程输入/输出反馈。由设置等效输入,将系统等效解耦为一阶、二阶线性子系统;经设置期望输出轨迹、定义系统跟踪误差、选择控制律,使全部跟踪状态保持有界,系统误差按指数规律收敛于零。仿真表明反馈线性化系统满足纵向着陆无误差要求,具有较强鲁棒性。
Input-output nonlinear equation was processed with feedback linearization of differential geometry in airplane automatic landing control system. The system was decoupled into 1 or 2 rank subsystem by setting the equivalent input. All the track statuses were kept in bound and error was converged to 0 according to exponent rule by setting hope-output locus, defining track error of system and choosing control rule. The simulation shows that feedback linearization system can content 0 error requirement of lengthways automatic landing.
