Review on different control techniques for induction motor drive in electric vehicle

Abstract

Now a day Electric vehicles (EV) are called future vehicles in place of internal combustion engines because of their working with pollution free and more efficient. This paper reviews various control strategies of induction motor drives (IMD) for EV applications. Efficiency and performance are the major considerations in selecting control algorithms for induction motor drives. Basically there are scalar control and vector control methods for IMDs. Scalar control technique has drawback of low performance. Conventional direct torque control (DTC) technique is one of the most preferable control technique for controlling torque and flux independently. But due the lower switching frequency in direct torque control leads to more flux ripple and torque ripples and it leads lower performance of induction motor drives.
