摘要
介绍了一类广义系统H∞控制器的设计过程.通过设计基于观测器的具有反馈增益变化的广义控制器,借助于带有广义约束的广义代数Riccati不等式(GARI),给出闭环广义系统容许且传递函数的H∞范数有界的充要条件.通过解带有广义约束的GARI得到该控制器的设计方法,并且控制器的参数矩阵只需使观测器容许.
This paper introduces the procedure for the design of H∞ controller for a certain class of descriptor systems. A controller with additive feedback gain variations based on an observer is designed. Then a sufficient and necessary condition is given through GARI with generalized constraint such that the resulting closed-loop descriptor systems are admissible and of H∞ performance. The design method of the controller may be obtained by solving GARI with generalized constraint. The parameter of the controller meets the condition that the observer is admissible.
