【摘要】 研究了一类T-S模糊广义系统的无源控制问题.通过矩阵分解方法,证明了这类系统容许的充分必要条件.在此基础上,将严格无源的概念引入到T-S模糊广义系统中,得到了使闭环系统容许、严格无源的充分条件,并将此条件用线性矩阵不等式(LMIs)表示.通过解这些矩阵不等式得到状态反馈增益矩阵.这个充分条件,可以一次判定系统的容许、严格无源.最后的数值算例说明所给方法的可行、有效.更多还原

【Abstract】 This paper is concerned with the problem of passivity control for a kind of T-S fuzzy descriptor system.A necessary and sufficient to test the admissibility for the system is proved by means of the matrix decomposition method.Based on the condition,the notion of strictly passive is proposed and the sufficient conditions,which make the closed-loop system be admissible and strictly passive,are obtained for the system.The conditions are expressed as linear matrix inequalities(LMIs),so the feedback gain matrix can be obtained by solving the LMIs.The sufficient conditions can check the admissibility and passivity of the considered system only once.An illustrative example is given to show the validity and feasibility of the proposed approach.更多还原
