结合系统响应速度的考虑,讨论由T-S模糊模型描述的不确定连续非线性系统具有指定衰减率的鲁棒保成本控制问题.基于扩展稳定性条件和等价投影引理,导出系统鲁棒保成本控制器存在的充分条件,并可将此控制器的最优设计问题转化为一组线性矩阵不等式的凸优化问题.研究表明:所设计的控制器不仅能保证闭环不确定模糊系统以衰减率α鲁棒渐近稳定,而且还给出了保成本上界的一个优化值.最后,数值示例验证了该设计方法的有效性. Considering the response speed of the system, we discuss the robust guaranteed cost control problem for a class of uncertain continuous-time nonlinear systems described by TS fuzzy model with specified decay rate. Based on extended stability conditions and equivalent projection lemma, the robust guaranteed cost The sufficient conditions for the existence of the controller and the optimal design of the controller can be transformed into a convex optimization problem for a set of linear matrix inequalities.The results show that the designed controller can not only guarantee the closed-loop uncertain fuzzy system with the decay rate α Robust asymptotically stable, but also gives an optimal value of the upper bound of guaranteed cost.Finally, numerical examples show the effectiveness of this design method.
