一、问题的提出模糊控制器的性能在很大程度上取决于所建立的模糊控制规则及其可调整性.因此,模糊控制规则的自调整是提高和改善模糊控制器性能的关键.由于模糊控制器的控制规则以解析形式描述,这就为设计具有在线自调整控制功能的模糊控制器提供了强有力的手段.基于模糊数概念建立了修正因子的模糊数模型,并对其插值.在对量化、比例、积分因子寻优后.能使所设计的模糊控制系统具有在线自调整控制规则的功能并具有良好的动态性能.本文还对模糊数模型有无插值运算两种方案进行了比较,并提供了仿真算例.
First, the problem proposed fuzzy controller performance depends largely on the established fuzzy control rules and its adjustability, therefore, the fuzzy control rules self-tuning is to improve and improve the performance of the fuzzy controller key.Because the fuzzy The control rules of the controller are described analytically, which provides a powerful method for designing the fuzzy controller with on-line self-tuning control function.Based on the fuzzy number concept, the fuzzy number model of the correction factor is established and interpolated. After the optimization of the quantification, proportion and integral factor, the designed fuzzy control system has the function of online self-adjusting control rules and has good dynamic performance.This paper also compares the two schemes of whether the fuzzy number model has interpolation operation , And provides simulation examples.
