Abstract: A control device for controlling the position of a rotor supported by active magnetic bearings is provided. The control device includes a trajectory planning module for generating a requested position, speed and acceleration; a feedback unit for generating a position feedback value and a speed feedback value; a first correction circuit for generating a first command signal according to the difference between the requested position and speed and the position and speed feedback value respectively; a feed-forward controller for generating a second command signal; an adder for adding first and second command signals and delivering a third command signal for a non-linear inversion circuit connected to the adder for generating flux command signals for the electromagnets, and a second correction circuit for generating voltage command signals for the power amplifiers which control the current flowing in the electromagnet coils of the active magnetic bearings.
