Abstract :
This paper presents a comprehensive analysis of the direct torque and flux control (DTFC) scheme for interior permanent magnet synchronous motor (IPMSM) drives. Closed-loop regulation of the torque and stator flux linkage are achieved via two independent proportional-integral (PI) controllers. The reference voltage vectors are generated by a space vector modulation (SVM) unit. A mathematical analysis of the DTFC principle is investigated in this paper. Furthermore, a rigorous design of the controller gains is undertaken. The design solution follows the integral of time multiplied by the absolute of the error (ITAE) criterion. Simulation and experimental results verify the effectiveness and robustness of the design approach.
