Control of induction motor drive using direct torque control with 12 sectors

the advantage of direct rorque control DTC of inverter -fed induction machine is high dynamic performance by means of very simple control sturcture using DTC technique we can eliminate complexity of field oriented control FOCbut it doesn’t drive the induction machine as well as FOCrecent researches have introduced improvements in DTC in this paper we present a new DTC method with 12 sectors in spite of 6sectors in classical DTC which make it more optimal .
