Efficient and high-performance control of induction motor

Abstract

This paper presents the backstepping-based controller design for an induc tion motor that’s a widely used propulsion source for electric vehicles (EV’s). The proposed control significantly improved the transient response or ac celeration of the vehicle because there is no coordinate transformation or orientation scheme is involved. The controller is directly designed in the stationary frame of reference and the multi-scalar model is used for decou pling the flux and torque of the induction motor. To relate the work with practical industry, the Chevrolet Bolt EV specifications have been utilized in vehicle dynamics and the acceleration profile of the proposed control tech nique has been analyzed and compared against conventional field-oriented control (FOC) and multi-scalar model direct linearization (MSM-DL) algo rithm in MATLAB/Simulink environment. The comparison results not only proved the extraordinary performance of the purposed controller but with less computational complexity due to the absence of any coordinate trans formation. The global stability proof of the proposed non-linear controller using Lyapunov stability criteria is part of the design process.
