Direct Torque Control with Space Vector Modulation
Simulated results for speed tracking performance for different reference speed level in
Fig. 5.54 are shown.
Figure 5.54. Simulated speed tracking performance with prefilter at the input for 10%, 20%,
50%, 100% of nominal speed. From the top actual speed, reference torque.
Investigation for influence of load torque in Fig. 5.55 is presented.
Figure 5.55. Simulated disturbance rejection performance of speed control loop for step load
change 50% of nominal torque. From the top electromagnetic torque, measured speed
