Speed Control of PMSM using Backstepping Method

Abstract

The Permanent Magnet Synchronous motor is a rotating electric machine where the stator is a classic three-phase stator like that of an induction motor and the rotor has permanent magnets. The speed controller of PMSM is designed using backstepping control. The Back stepping control is a systematic and recursive design methodology for nonlinear feedback control.A PMSM is modeled in the dqspace and an inverter is used for driving the motor. The switching pulses for inverter are generated using Space Vector Modulation (SPWM) method. The effectiveness of the proposed control scheme is verified using simulation.
