Abstract
Sliding mode control with disturbance estimator scheme is proposed for the control of a maglev vehicle. The conventional sliding mode control requires a priori knowledge of the upper bounds of parameter variations and disturbances to assure robustness, but it is hard to know the upper bounds of guideway disturbances like guideway irregularity and guideway deflection in a maglev vehicle. A sliding mode control with disturbance estimator, which offers a robust control performance without a priori knowledge about the disturbances, is derived to maintain the desired robustness and minimize the effect of guideway disturbances. Simulation results of the proposed controller are given to illustrate the effectiveness of the proposed scheme.
