Hello,  Srikant!

The easiest way to reverse speed of induction motor is to change two phases of the stator winding. But this way does not provide any prediction of the torque (actually, I don't understand fully what exactly you mean after "predictive torque technique"). Generally, to restrict the torque (I equal terms of "restrict" and "predict" for this question) means that some controllable device (frequency converter, soft start, etc.) has to be implemented. This device, designed by semiconductor elements or old resistive ones, adjusts the voltage or current of the stator winding (frequency converter do it with frequency simultaneously) or the rotor winding (control by the rotor winding is not widespread). As a result, the torque of an induction motor is controlled (or restricted, or predicted) by means of that.

I hope I get the core of your question clear. Best wishes!
