摘　　要：在建立了转子高速旋转时电磁轴承系统的模型基础上 ,针对此系统的多变量模型 ,采用了多变量模糊解耦方法进行控制研究。文中推导了有效的降维模糊关系矩阵 ,得出了四输入四输出的多变量模糊系统的输出算法 ,并进一步考虑了加上输入变量导数的情况下算法的推导。Based on the system model of the AMBs when it's rotor runs at high speed, a control method is investigated according to the multivariable model in this paper. As to the multivariable system model, a fuzzy decoupling method is used, and the valid fuzzy relation matrix with lower dimension is examined. The fuzzy decoupling method of the multivariable system with four-input variable and four-output variable is discussed, and the arithmetic method of the output variable is derived. And farthermore, the derivative of the input variable is taken into account, and the arithmetic method is derived as well.
