A general approach to direct torque and flux control of induction motor fed by VSI is presented in the paper. The inverter switching patterns are generated as a function of the reference values both of the electromagnetic torque and of the controlled flux. In particular, the proposed control algorithm is independent on which kind of flux is controlled, rotor or stator one. The results obtained by means of a real time simulation show that the proposed control strategy allows to obtain a very fast and accurate response of the drive.

Abstract
A general approach to direct torque and flux control of induction motor fed by VSI is presented in the paper. The inverter switching patterns are generated as a function of the reference values both of the electromagnetic torque and of the controlled flux. In particular, the proposed control algorithm is independent on which kind of flux is controlled, rotor or stator one. The results obtained by means of a real time simulation show that the proposed control strategy allows to obtain a very fast and accurate response of the drive.File in questo prodotto:
