| 摘 要： | 针对状态不完全可测的一类不确定连续状态非线性系统的保性能控制问题,采用T-S模型对其进行建模。根据李雅普诺夫稳定性理论,基于线性矩阵不等式(LMI),利用分散化并行分布补偿(PDC)的方法设计了基于观测器的控制器,给出了实现该非线性系统保性能控制的充分条件。

| Abstract: | Against the guaranteed cost control problem for a continuous-time nonlinear system in the presence of parametric uncertainties,the Takagi-Sugeno(T-S) fuzzy model was adopted for fuzzy modeling of the system.According to Lyapunov stability theory,the scheme of decentralized PDC(Parallel Distributed Compensation) fuzzy control was designed via LMI method,and apart from the above,the sufficient condition that ensures guaranteed cost control of nonlinear system was proposed. |

| Keywords: | T-S model linear matrix inequalities parallel distributed compensation guaranteed cost control |
