Nonlinear Adaptive Control of Conical Magnetic Bearings

Abstract

We design an nonlinear adaptive control for a conical magnetic bearing system using the structure algorithm of Hirschorn and Singh and its adaptive version due to Ghanadan and Blankenship. Simulation results are presented and compared with the optimal linear controller of Mohamed and Emad. The nonlinear controller improves transient and forced response. The nonlinear adaptive controller also improves performance with uncertainty in the rotor angular velocity and stabilizes the system over a greater range of error than the nonlinear controller without adaptation.
