A hybrid foil magnetic bearing is a combination of the foil bearing and magnetic bearing, which have the advantages of both and can also share loads between them. In this paper, the model of a rigid rotor supported by two hybrid foil magnetic bearings was established, and a controller based on the Linear Quadratic Gaussian control law was designed for this new type of bearing. Finally, Simulation was performed to verify the performance of the rotor-bearing system, and the results show that the system could work well at situations with strong perturbation forces.
