| 摘 要： | 针对一类用模糊动态模型描述的非线性时滞系统，提出一种基于模糊性能评估器的新型鲁棒控制方案，模糊性能评估器用于检验模糊模型及其控制率的有效性，以线性矩阵不等式的形式，给出了模糊性能评估器和模糊控制器存在的充分条件；分析了闭环控制效果与模糊性能评估器性能之问的关系，从而说明该方法为模糊控制系统提供了一种无损调试方法，最后以CSTR系统为例，通过仿真验证了该方法的有效性。

| Abstract: | A novel control scheme is proposed based on fuzzy performance evaluator (FPE) for a class of nonlinear time-delay systems described with fuzzy dynamic model. The FPE is used to verify the validation of fuzzy model and control law. Sufficient conditions for existence of fuzzy performance evaluator and fuzzy controller are derived through finding the feasible solutions of some linear matrix inequalities (LMIs). The relationships between the performance of FPE and the closed-loop system are analyzed, which means that it offers a nondestructive debug method for fuzzy control system. The CSTR system is used to show the effectiveness of the control scheme. |
