摘　　要：考虑到BTT导弹存在较大的耦合和不确定性,传统频域控制理论以及三通道独立设计方法不再适用于自动驾驶仪的设计。为此,研究了BTT导弹横侧通道H∞鲁棒控制器的设计问题,用以抑制不确定性、外来扰动以及通道间耦合给系统带来的不利影响。首先分析了H∞鲁棒控制器设计中存在的关键问题,包括不确定性的分析及加权函数的选择;然后通过建立包含未建模不确定的被控对象、引入加权函数,得到了扩展的广义受控系统,利用Matlab鲁棒控制工具箱设计了BTT导弹横侧通道的H∞鲁棒控制器;最后通过仿真验证,表明设计的H∞鲁棒控制器具有良好的控制性能和鲁棒性。Considering the larger coupling and uncertainty exist in the BTT missile, traditional frequency domain control theory and three - channel independent design method can no longer apply to the autopilot design. The design of H - infinity robust controller was studied for the Lateral model of BTT missile. Firstly, the key points of the design were proposed including the analysis of uncertainty and the selection of weighting functions ; secondly, an augmented model was established via introducing the unmodeled dynamics and weighting functions, and an H - infinity controller was designed with MATLAB Robust Control Toolbox. The simulation results show that the controller has high performance and robustness.
