摘　　要：磁悬浮系统鲁棒模糊控制器设计,基于Product-Sum模糊控制和H∞控制理论,使用Singleton模糊化、Product模糊推理及Center-Average法解模糊,并以三角型的隶属函数作为输入集合的隶属函数。其仿真验证了该控制器在处理系统本身的非线性及外部干扰时,具有稳定性和很强的鲁棒性。The robust fuzzy controller of magnetic levitation system is designed according to the Product-Sum fuzzy control theory and H^∞control theory,Singleton fuzzification, Product fuzzy reasoning method and Center-Average fuzzy were used in the controller, and trigonal membership functions were used as input collect of membership functions. The simulation of the controller used in magnetic levitation system shows that the controller has the stability and very strong robustness when processing nonlinear of system and external disturbance.
