Robust Position Control of SM-PMSM Based on a Sliding Mode Current Observer

Abstract

This paper propose a reduced-order sliding mode controller based on a sliding mode observer applied to a Surface Mounted Permanent Magnet Synchronous Motor (SM-PMSM). The external disturbances are considered in the design of the controller in order to provide good results and accuracy of the system. Additionally, the corresponding observer is used to estimate the rotor position. Simulations and experiment results are shown to confirm the effectiveness of the proposed controller and observer.
