摘要
研究了高超声速飞行器鲁棒飞行控制器设计以及飞行控制系统的仿真验证问题,通过选择适当的加权函数矩阵,确定广义受控对象。线性矩阵不等式(LMI)技术是控制领域中研究问题的有效工具,控制器的分析与综合等问题可转化为LMI问题的求解,采用基于线性矩阵不等式的H∞控制器设计方法,设计了鲁棒控制器。仿真结果表明所设计的飞行控制系统具有鲁棒性,能有效地抗飞行过程中存在各种各样的干扰及摄动,很好地满足了飞行控制系统性能指标。
The design of robust controller for hypersonic vehicle and the simulation of the light control system are investigated. The selection of weighting function matrixes for general tracking control problems is discussed. LMI technique is a kind of effective toot for studying all kinds of problems in the field of control theory and application. The problems of robust control analysis and synthesis can be converted to solving LMI problems. A robust flight controller is designed by using linear matrix inequality （LMI） based H∞ controller design method. The simulation and computation results show that the designed flight control system has an effective ability for anti - disturbance invariant systems,has stability and performance robustness, and it satisfies the specifications and technical requirement.
