摘　　要：系统地分析了在标准H∞控制问题中设计鲁棒状态反馈控制器时较为普遍使用的Riccati法和LMI法 ,比较了两种方法的三点区别。并举例分别设计两种状态反馈控制器 ,对含有控制器的系统进行仿真研究。Riccati approach and LMI approach are analyzed systemically,which have been currently used in standard H ∞ control problems,while designing the robust state feedback controllers.Three differences are discussed.The controllers based on these two methods have also been designed according to a concrete example;the simulations are given too,which demonstrates the superiority of LMI-based approach.

关 键 词：H控制 Riccati法 LMI法 状态反馈控制器
