| 摘 要： | 针对空天飞行器(ASV)的姿态系统的非线性、强耦合和不确定性,提出了一种分散模糊滑模变结构控制方法.首先基于反馈线性化方法将ASV姿态系统解耦成3个独立的子系统;然后应用模糊滑模变结构控制方法分别设计了各子系统的姿态控制器.通过结合模糊控制与滑模变结构控制,有效抑制了ASV姿态系统的建模误差以及外部干扰.理论分析和仿真研究表明,所提方法具有控制精度高、鲁棒性强、便于工程实现等优点.

| Abstract: | Considering the characteristics of nonlinearity,strong coupling and uncertainty of the aerospace vehicle's attitude system,a fuzzy slide mode variable structure control method is proposed.Based on the feedback linearization technique,the system was firstly decoupled into three independent SISO subsystems,and then attitude controllers for each subsystem were designed by use of fuzzy slide mode variable structure control method.Modeling error and unknown disturbances are restrained effectively by combining fu... |
