Force Controllers for AMB Systems with Position and Current Feedback

Abstract:

In this paper, the state-of-the-art AMB controller structure, with an outer centralized position control loop with reference currents and inner current control loops, is replaced with an outer control loop with force references and inner flux control loops. The linearization of the force actuators and different control schemes of the centralized outer control for the radial suspension are considered. The operation of the proposed control under a zero bias is verified by simulations. The proposed control solution can achieve a dynamic performance comparable with that of a controller with the classical bias current.
