摘　　要：针对一类不确定T-S模糊动态系统,利用线性矩阵不等式方法,研究了一类非线性系统H∞动态输出反馈控制,且满足闭环极点配置要求.采用动态并行分布补偿进行控制器的设计,考虑了受控输出变量中的参数不确定以及控制器中控制系数不为零的情况,较以往设计更具一般性.给出了模糊闭环系统的全局稳定性充分条件,并将其转化为线性矩阵不等式形式.最后,以复杂非线性陈系统为仿真算例。The design of a H∞ dynamic output feedback controller,satisfying the configuration of closed-loop poles was studied for a class of uncertain T-S fuzzy dynamic systems,via linear matrix inequalities（LMIs）.The control laws are in the form of so-called dynamic parallel distributed compensation（DPDC）which is essentially for the design of nonlinear dynamic feedback controllers.Such a design is more general than previous ones since the parameter uncertainties in controlled output variables and the non-zero control coefficients of controller are both taken into account.Then,the sufficient condition is given to the global stability of closed-loop fuzzy systems with the condition transformed into LMI form.The effectiveness of the proposed approach is successfully verified through an example of complex nonlinear Chen＇s system by means of the numerical simulation.
