direct torque control
no vote
The vector control of PMSM allows them to be controlled as the same manner as a separately
excited DC motor where the torque is directly proportional to the product of armature
current and the excitation flux. Here in the case of PMSM the torque control is
achieved by controlling the torque component of current and flux component of current
independently. This work presents the basic direct torque control scheme and the DTC with
space vector modulation technique (DTC-SVM) to improve the performance of Direct
Torque Control of Permanent Magnet Synchronous Motor (PMSM) The mathematical
model of PMSM with its working principle is presented. Instead of switching table and
hysteresis controller, this technique is based on voltage predictive estimation and space
vector pulse width modulation. This control scheme improves the torque and flux response
and has a constant switching frequency, which reduces the torque and flux ripples with a fast
response. The MATLAB/ Simulink Software
