| Abstract: | To the bearingless induction motor system with multi-variable,nonlinearity and high coupling,the control method based on inverse system theory is used to realize the decoupling control.The principle of the bearingless induction motor is expounded briefly,and the mathematic models of radial suspension force and the rotation part of motor are deduced.Then the nonlinear inverse decoupling control is used for the torque windings.And the stable levitation can be assured by using the air gap flux linkage of motor... |
