摘　　要：研究了变时滞参数不确定T-S模糊广义系统的鲁棒H∞控制问题。在给定这类系统的正则、无脉冲和渐近稳定性定义的基础上,依据Lyapunov理论,证明了使闭环系统二次稳定并且具有适当鲁棒H∞性能指标的充分条件。用线性矩阵不等式方法给出了这种充分条件,从而可以通过解矩阵不等式获得状态反馈增益矩阵,算例说明了这种方法的有效性。This paper discusses the problems of robust quadratic stability and robust H∞ control for a class of fuzzy descriptor systems with time-varying delay and parameter uncertainties. Base on the system definition about regularization,no-impulse and asymptotic stabilily, according to the theory of Lyapunov,the sufficient conditions,which maintain the stability of the closed-loop and satisfy the H∞-performance are given. These conditions are expressed via LMIs. So the feedback gain matrix can be obtained easily by solving the LMIs.The effectiveness and feasibility are verified by an example.
