摘　　要：针对三维模糊控制器规则多,结构复杂,难以实现的问题,提出了一种简化的三维模糊控制器。该方法是把三个输入量分别为偏差、偏差变化、偏差的偏差变化的一维模糊控制器加权融合实现简化的三维模糊控制器。并提出了根据不同类型的被控对象设置三个加权系数。加权系数具有粗调、细调和微调的作用,类似于传统PID调节器的比例、积分和微分,实现对系统静差的消除。Because of many rulers, complex structure and difficult to achieve for three-dimensional fuzzy controller, simplified three- dimensional fuzzy controller is proposed. Three one-dimensional fuzzy controllers with deviation, deviation change, and deviation＇s deviation change inputs are weighted fusion to realize simplified （S） three-dimensional fuzzy controller in the method o And it puts forward methods of weighting factors setting for simplified （S-type） three-dimensional fuzzy controller according to different control plants. Weighting factors have function of wide, fine and precision adjusting system performance respectively,which are similar to proportion, integral and differential coefficient of PID controller.
