摘　　要：提出一种二维PID模糊控制器,其结构形式简称为fuzzy PI+fuzzy ID型.根据fuzzy PI和fuzzy ID控制器的图解说明,确定该fuzzy PI和fuzzy ID控制器的模糊控制规则的相似性.理论分析表明,该PID模糊控制器除具有常规PID性能外,还具有非线性等特点.仿真结果表明,与常规PID和fuzzy PI控制相比性能更优.A brand-new two-dimension PID fuzzy controller, fuzzy PI＋ fuzzy ID, is proposed. By comparing the illustration of the fuzzy PI and fuzzy ID, the similarity of the two corresponding fuzzy control rules is ensured. The theoretical analysis shows that the PID fuzzy controller possesses the feature of nonlinearity besides that of the traditional PID. The simulation research result shows that its control feature is better than that of the traditional PID and fuzzy PI.
