Abstract

We present in this paper a comparative study between two control strategy of Induction
Motor that propels an electrical vehicle: Direct Torque Control (DTC-SVM), and Predictive
Direct Torque Control (MPDTC). The first algorithm based on load angle control is developed.
The use of simple equations to obtain the control algorithm makes it easy to understand and
implement. Fixed switching frequency and low torque ripple are obtained using space vector
modulation. This control strategy overcomes the most important drawbacks of classic DTC.
