Popis: With rotor field oriented control mathematic model of the bearingless induction motor, a nonlinear controller based on state feedback linearization is designed such that the nonlinear system with multivariable and strongly coupled motion is reduced to decoupled linear subsystems including its speed and rotor flux as well as two rotor displacements. Expert-PID controllers are designed to these decoupled linear subsystems. To verify the effectiveness of the control scheme, some simulations were carried out and the results show satisfactory static and dynamic performances of the system which enables stable suspension of the bearingless induction motor.
