多不确定性战术导弹鲁棒控制器设计研究

Design of Robust Controller for Multi-Uncertain Tactical Missile

研究了包含多种不确定性的战术导弹鲁棒控制器设计问题;首先介绍了μ分析与μ综合理论,给出了通过D-K迭代设计鲁棒控制器的方法;进而通过分析系统中存在的多种不确定性及其对受控系统的影响、建立包含多种不确定的被控对象、引入合适的评价权函,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战术导弹俯仰通道鲁棒控制器;最后通过数值仿真,验证了设计的鲁棒控制器满足系统设计的性能指标要求,并且对系统中存在的多种不确定性和扰动具有较强的鲁棒性。

The design of robust controller for the tactical missile which contains multi--uncertainties is studied. Firstly, the u analysis and u synthesis theory and the D--K method is introduced; secondly, an augmented model is established via analyzing the uncertainties and the effect to the controlled object, building the multi--uncertain controlled model, introducing the weighting functions, and a robust controller for the pitch channel of a tactical missile is designed by MATLAB robust control toolbox. The simulation results show that the robust controller meets the requirements of the control performance and reaches high robustness.
