Control of Induction Motor Drive Using Direct Torque Control with 12 Sectors

Abstract

The advantage of Direct Torque Control (DTC) of inverter-fed Induction Machine is high dynamic performance by means of very simple control structure. Using DTC technique, we can eliminate complexity of Field Oriented Control (FOC); but it doesn’t drive the Induction Machine as well as FOC. Recent researches have introduced improvements in DTC. In this paper we present a new DTC method with 12 sectors, in spite of 6 sectors in classical DTC, which make it more optimal.
