Análise Comparativa de Técnicas de Controle Direto de Torque e Controle Preditivo de Torque Aplicadas em Tração Elétrica

This paper compares three direct control strategies por induction machines, analizing it’s performance for electric vehicle tration. The stretegies analysed are DTC, DTC with PI controllers and PTC, driving an induction motor with a mechanical dinamic model of a vehicle as the load. Simulation shows that all controllers as suitable to use in EV traction, but the modulation results in better current THD and torque/flux ripple. Between the classic DTC and the PTC, the predictive controller is a better choice, with smaller THD and torque/flux ripple.
