Abstract :
The torque control of an asynchronous motor fed by a voltage source inverter (VSI) is performed by evaluating, by means of a microprocessor, in each sampling interval the voltage space vector which gives rise to a mean value of the electromagnetic torque just equal to the imposed one. The correspondent modulation technique for the VSI is described. The results obtained by means of a numerical simulation show a very good behavior both in steady state and in transient operation, with particular reference to the accuracy and the quickness of the drive response
