Abstract
A method for setting up system equations and the control design problem for a horizontal-shaft-type magnetic-bearing system are discussed. We obtain the fundamental equations of the motion of the rotor by adapting the dynamic theory of flight problems to this system and then obtain the system equations with gap-length displacements and controlled currents taken as the state variables. By constructing an integral-type control system, we are able to maintain the rotor in the center position in the final steady state.Keywords
