Design and Modeling Improved Direct Torque Control of Induction Motor Drive

Omid Moradi; Mohammad Reza Alizadeh Pahlavani; Iman Soltani

This paper studies most commonly used electric driving method of induction motors (IM). Direct torque control (DTC) have been widely commercialized in induction motor drives, with each being favored by its supporters. In this paper, the dynamic performance of these drives for an electric vehicle application is examined, and sensitivities to parameter variations affecting this dynamic performance are explored by jacobian matrix in which the sensitivities of torque, speed, and other desired variables or outputs are estimated relative to change in motor parameters. Key performance measures include torque and speed transients. The switching scheme of these drive is a switching table. Both the overshoot and the settling time of DTC are really small.
