一种新的参数在线自调整模糊控制器

A New Algorithm of Parameters On-line Self-tuning for Fuzzy Controller

在分析了模糊控制器的量化因子和比例因子对系统动态性能影响基础上,在增量型二维模糊控制器中,基于T-S模糊模型设计了在线调整量化因子和比例因子模糊器,实现了一种新的模糊控制器参数在线自调整的方法.对大纯滞后对象的仿真表明,系统的动态性能获得了明显改善.

Based on the analysis of the effects of measured factor and proportional factor in the fuzzy con- troller to the system performance,the fuzzy controller of on-line adjustment of measured factor and proportional factor based on T-S fuzzy model is designed in the two dimension increment-fuzzy-controller, the new algorithms of parameters on-line self-tuning for the fuzzy controller is realized. Simulation of industry process with time delay shows that the control algorithms obviously improved system dynamic performance.
