Super-twisting sliding mode control of synchronous motors

Abstract

Based on a nonlinear complete order model of a synchronous motor, a robust second order sliding mode observer based control scheme is proposed. To design this scheme a super-twisting sliding mode control and adaptive backstepping techniques, are implemented. A nonlinear reduced order observer is designed for estimation of the rotor fluxes. The simulation result shows the effectiveness of the proposed controller. Copyright © 2012 CCE.
