Abstract :
In this paper, the principle of bearingless synchronous reluctance motors is explained and a mathematic model of control system is deduced. The main problem in the control system is the coupling between the radial force and electromagnetic torque, and between the two radial forces in x- and y-direction. A decoupling method based on the feed-forward compensator is designed to decouple those variables. Proposed control system has been simulated in Matlab/Simulink environment. Simulation results have validated that stable suspension operation and the decoupling can be realized successfully with this method.
