摘要: 针对导弹姿态跟踪系统,设计了一种基于线性矩阵不等式( LMI)的鲁棒H∞ 输出反馈姿态跟踪控制器。在被控对象参数变化剧烈的情况下,基于H∞准则,通过求解LMI,得到只运用输出进行反馈控制的鲁棒控制器参数。为使鲁棒控制器达到实际应用的要求,对控制器进行了改进,并采用导弹6自由度非线性数学模型进行了验证仿真。仿真结果表明,这种鲁棒输出反馈控制器在具有良好的姿态跟踪特性的同时,还具有良好的抗干扰性能。

Abstract: An attitude tracking controller based on Ho0 robust output feedback for a certain missile was designed by solving linear matrix inequality (LMI). On condition that the model parameters change se?riously, the parameters of a robust controller just including output feedback were obtained by solving LMI based on H00 criterion. In order to satisfy the applied requirement of the robust controller, it was modified and simulated by six freedom nonlinear mathematic model. The simulation results show that the robust output feedback controller possesses good performances of attitude tracking and antijamming.
