A Novel space vector modulated DTC scheme of induction motor drive with a single PI controller for electric vehicles

Facilitating instantaneous torque and smooth speed of Electric vehicle (EV) largely relies on modulation scheme employed type controller used for motor drive system. The DTC-SVM (Space Vector Modulation) approach with two PI controllers has an excellent steady state transient response. However, there is still a need to reduce stator current ripples in induction application vehicle. This paper presents new minimize harmonics, ripple appropriate gain value controller. Good performance the achieved using single Both flux are controlled effectively less ripple. In this study, obtained at full, one-half one-fourth rated speeds value. work analyzes operation unit step change command various rotor speeds. Space Pulse Width Modulation (SVPWM) constant switching frequency presented.

Total Harmonic Distortion (THD) input different fluxes tabulated classical, proposed found be robust good characteristics validated vector trajectories.
