Abstract

In this paper, we propose a control method for an air bearing motion stage complemented eddy current braking. The proposed control scheme uses two control inputs to handle the nonlinear air bearing system: one is P control plus a feedforward term and one is eddy current feedback. The stability analysis is discussed involving two cases: (1) accurate model, (2) uncertain model. The experimental results are given to further verify the effectiveness of the proposed method.
