Analysis of direct torque control in permanent magnet synchronous motor drives
TL;DR: In this paper, direct torque control (DTC) for permanent magnet synchronous motor (PMSM) drives has been investigated, and it is proved that the increase of electromagnetic torque in a permanent magnet motor is proportional to the angle between the stator and rotor flux linkages, and therefore the fast torque response can be obtained by adjusting the rotating speed of the stators flux linkage as fast as possible.
