摘要
针对一类变体飞行器控制问题,提出一种平滑切换线性变参数(LPV)鲁棒控制器设计方法.建立变体飞行器切换LPV模型,设计平滑切换控制器,其中偶数子系统控制器由相邻两个子系统控制器线性插值得到.给出保证切换LPV系统指数稳定且具有一定鲁棒性能的充分条件,由于考虑了调参变量的渐变特性,所得切换律没有平均驻留时间的限制.仿真结果表明,所提出方法使得飞行器系统既具有良好的稳定性和鲁棒性,又能实现平滑切换.
A smooth switching linear parameter varying（LPV） robust controller is proposed for the control problem of a class of morphing aircraft. The LPV model of morphing aircraft is developed, and the smooth switching control law is designed,in which the controllers of the even subsystems are smoothly scheduled between the two controllers of adjacent subsystems.Then, a sufficient condition for ensuring the LPV system exponential stable and having a certain robust performance is presented. Considering the scheduling parameter changing gradually, a switching law without constraint on average dwell time is obtained. Simulation result shows that, by using the proposed method, the aircraft system not only has good stability and robustness, but also can switch smoothly during morphing.
