Sensitivity Analysis of Complex Systems Based on T-S Fuzzy Models

针对输入具有互联的系统的灵敏度分析常常会产生不正确结果的问题,提出一种获取这种复杂系统灵敏度信息的方法.这种方法首先需要建立系统的基于自适应神经模糊推理系统的T-S模糊模型以及各个输入的T-S模糊模型;然后从这些模糊模型抽取出灵敏度信息.同时讨论了这种输入具有互联的系统的模糊建模方法.仿真实例验证了所提出的抽取灵敏度信息方法的正确性.For the complex system with interrelated inputs, a method of extracting sensitivity information is proposed to overcome the wrong results obtained when using existing sensitivity analysis method. This method requires firstly generating T-S fuzzy models of system and each input based on adaptive neuro-fuzzy inference systems (ANFIS) architecture,then sensitivity information is extracted from these fuzzy models. An approach to obtain fuzzy models of the system with interrelated inputs is proposed. Simulation result shows the validity of the proposed method of extracting sensitivity information.福建省自然科学基金项目(A0410005
