Performance analysis of FOC and DTC for PMSM drives using SVPWM technique

Abstract

The aim of this article is to present the performance of field oriented control (FOC) and direct torque control (DTC) of a permanent magnet synchronous motor (PMSM) using the technique of space vector pulse width modulation (SVPWM). First, after developing a mathematical model of PMSM we present the principle of space vector modulation technique to use in commands. Secondly, we developed a field oriented control and direct torque control strategy. Finally, we proposed a failover system between direct torque control and field oriented control in the event of default or loss of information.
