This paper describes a novel compensating approach for the self-sensing (gap-sensor-free) Maglev system with controlled-PM electromagnets. The proposed compensator consists of two parts: the hybrid observer and the robust controller. The hybrid observer combing a reduced-order observer and an external-force observer can estimate the steady-state gap variation even with payload change. A new reaching-law-based variable structure control (VSC) method is employed to the robust controller synthesis for enhancing system stability. The performance of the overall compensator is tested with a single-degree-of-freedom Maglev system. Results obtained indicate the good response of the proposed compensating scheme.
