Using dSpace Systems for Torque Control of Asynchronous Motor Drive

Abstract

We present in this paper a vector control scheme for an inverter-fed asynchronous motor, implemented into a dSpace system. The design of the control scheme is carried out considering the model of the motor in a stationary two-phase frame of reference. The rotor flux linkage, the electromagnetic torque, and the reactive power are estimated by only using the measure of the three-phase currents and voltages.
