Abstract :
This paper presents two algorithms: one for sensor runout compensation, and the other for compensation of both sensor runout and mass unbalance in magnetic bearings. The algorithms, developed using Lyapunov´s method, guarantee asymptotic stability of the rotor geometric center about the origin and convergence of unknown parameters using persistent excitation. Both algorithms have advantages over existing methods. Simulation results are presented to demonstrate efficacy of the algorithms
