一种Backstepping模型参考鲁棒飞行控制律的设计

提出了一种Backstepping模型参考鲁棒飞行控制律的设计方法。方法的主要特征是：在仅需要输入输出信号的情况下，即使系统参数未知且存在未建模动态和非线性因素干扰，系统仍能保证较强的鲁棒性，获得良好的跟踪效果。具体给出了飞机纵向通道短周期控制的设计方案，同时讨论了其他复杂模态下该方案的扩展方法。对上述方案的数值仿真显示了该方法良好的跟踪性能。

Backstepping model reference robust controller design for flight control

A Backstepping model reference robust control (MRRC) is used to solve the flight control problem. The main feature of the scheme is that only the plant input and output signals are needed and, even with the existence of plant uncertainty, unmodeled dynamics and non linear disturbance, both the tracking performance and the control effort can be improved significantly. The detailed design of longitudinal short period mode of an aircraft is given chiefly, and the design procedure for other modes whose relative degree is greater than one is discussed, too. The simulation results show that a perfect tracking performance can be achieved by using the design scheme.
