摘要:
对于具有不确定性的控制系统,如何保证控制系统的设计能够具有鲁棒性,同时又达到最优的控制性能,[μ]综合方法以完备的结构奇异值理论为基础,给出了这一问题的最优解。导弹受控飞行于稠密大气层时,其自动驾驶仪正是这样一种要面对多种不确定性因素的控制系统,为使导弹控制在这种情况下达到鲁棒最优,将[μ]综合方法用于导弹自动驾驶仪设计,并对设计结果进行了仿真验证,结果分析表明采用该方法对于导弹气动不确定性具有更好的鲁棒效果。

Abstract:
Method of [μ] synthesis based on self-contained structured singular value theory provides a resolution for control system with uncertain character. It makes the control system to have enough robustness and optimal control performance. When the missile is flying in the dense aerosphere, the autopilot is such a control system facing a lot of uncertain elements. To obtain the optimal robustness in such case, the method of [μ] synthesis is used to design the autopilot in this paper. Also the results of simulation are tested and analysed. And the final analysis indicates the adopted controller has a better robust effect than the traditional PI controller.
Key words:  Robust Control  Method of [μ] synthesis  D-K iteration algorithm  Autopilot
