摘要
首先介绍了多变量非线性系统基于反馈线性化的滑模控制方法 ,用它设计的控制律由反馈线性化控制和滑模控制两部分构成 ,然后用其为某型直升机的垂直飞行模态设计了控制律 ,并进行了系统仿真研究。仿真结果表明 ,所设计的控制律能保证直升机稳定跟踪给定输入。这说明基于反馈线性化的滑模控制方案较好地解决了该型直升机垂直飞行的控制问题。
A sliding mode control approach based on feedback linearisation is presented and the control laws designed by it are composed of two psrts:one is feedback linearisable control and the other is sliding mode control.Using this approcah, a control system is designed for a helicopter vertical flight mode and simulation works are done.The results show that the controlled helicopter can track the given trajectories stably and the proposed control scheme can solve the control problem of the helicopter vertical flight satisfactorily.
