| 英文摘要 |
| The adaptive inverse decoupling control based on nonlinear adaptive filter for levitation system of bearingless
induction motor (BIM) is investigated. Nonlinear adaptive filters are used to build the model and the inverse model of
the system. Based on the inverse model, the adaptive inverse controller which is cascaded in front of levitation system
is designed by using the improved least mean square (LMS) algorithm to adjust the weighting factors online. Compared
with the traditional control method, the flux information is not needed to be transferred with the torque control system.
As a result, the mutual restriction between torque windings and levitation windings is avoided. Finally, we demonstrate
the effectiveness of our proposed method with simulations. This method realizes not only the establishment of the system
model and the inverse model, but also the decoupling control of levitation forces of two degrees of freedom. |
