Permanent magnet synchronous motors (PMSM) are extensively used in high-performance industrial applications. The electromagnetic torque in a PMSM is proportional to the angle between the stator and rotor flux linkages. Therefore, high dynamic response can be achieved by means of direct torque control (DTC). The main advantage of DTC is its structure simplicity, since no coordinate transformations...
The permanent magnet synchronous motors (PMSM) are extensively used in high-performance industrial applications. The electromagnetic torque in a PMSM is proportional to the angle between the stator and rotor flux linkages. Therefore, high dynamic response can be achieved by means of direct torque control (DTC). However, because the rotor flux linkage is fixed on the rotor of PMSM, high torque ripple...
The paper presents a discrete space vector pulse-width modulation applied to direct torque control (DTC) of PMSM, which is a compromise between performance and low complexity because the use of look-up tables. DSBM is able to produce more voltage vectors than are available with the classical DTC, by using different look-up tables depending on the value of the emf voltage induced in the stator windings...
