摘　　要：基于T-S模型设计模糊PID控制器,在分析量化因子和比例因子对系统性能的影响基础上,基于T-S模型制定了在线校正量化因子和比例因子模糊规则,实现了模糊PID控制器在线自校正。对大纯滞后对象的仿真表明,该控制器明显改善系统的动态性能。This paper presents the design of a fuzzy PID controller based on the T-S fuzzy model, and analyses the effects of both quantized factor and proportional factor on the system performance. This analysis can help forward laying down a fuzzy rule for the on -line adjustment of the quantized factor and the proportional factor, thus realizing the on-line self-tuning of the fuzzy PID controller. The simylation of an industrial process with time delay shows that the control algorithm can improve the dynamic performance of the system.
