英文摘要：

According to the serious nonlinearity and highly coupling of variables in bearingless induction machine, the traditional control method cannot meet the requirement, a kind of double fuzzy controller based on Mamdani method was proposed. The mathematical mode of bearingless induction machine was established and the mathematical relationship among each variable. Then new type controller was designed, including the overall structure design, the design of double fuzzy controller. According to the MATLAB/simulink simulation, the results show that the novel controller based on double fuzzy control has excellent dynamic and steady performance. It has better control performance, which verifies the feasibility of the design.
