Abstract :
In this paper we utilize a nonlinear model of a six degree of freedom (DOF), active magnetic bearing system to develop a nonlinear backstepping-type controller for the full-order electromechanical system. The controller requires measurement of the rotor position, rotor velocity, and stator current, and achieves global exponential rotor position tracking
