Backstepping-Based Nonlinear Robust Controller for AMB Spindle

Abstract:

In this paper, backstepping method is used to handle the nonlinear factors for magnetic bearing spindle systems, resulting in the design of a nonlinear robust controller to make the system in equilibrium with the global uniform asymptotic stability. Meanwhile, considering the uncertainty in the system model, the impact of uncertainty is introduced in the design process, so that the system has certain robustness. Simulation results show that this method can have a good control effect in the nonlinear magnetic bearing spindle applications..
