Abstract :
This paper discusses the control of stator flux and torque in the surface permanent magnet synchronous motor (SPMSM) direct torque control (DTC) system. The study shows the angle between stator flux vector and the applying voltage vector determines the dynamic behavior of stator flux and the angle between rotor flux vector and the applying voltage vector determines the dynamic behavior of torque. Two optimal voltage vector selection strategies for the SPMSM DTC system are proposed. Simulation results testify theoretical analysis.
