<strong>Direct</strong> <strong>Torque</strong> <strong>Control</strong> <strong>with</strong> <strong>Space</strong> <strong>Vector</strong> <strong>Modulation</strong><br />
The behavior <strong>of</strong> the flux control loop was tested using SABER simulation package. The<br />
model created in SABER takes into account the whole control system, which include<br />
real models <strong>of</strong> inverter and permanent magnet synchronous motor.<br />
The flux step response is shown in Fig. 5.12., when parameters <strong>of</strong> P flux controller<br />
designed for sampling time T s<br />
= 200µ s were used for control plant for different<br />
sampling times T s<br />
= 50µ s , 100µ s , 200µ s , 400µ s , which correspond to switching<br />
frequency f<br />
s<br />
= 20kHz, 10kHz, 5kHz, 2.5kHz.<br />
Figure 5.12. Flux tracking performance for different sampling time T<br />
s<br />
= 50µ s , 100µ s ,<br />
200µ s , 400µ s ( f<br />
s<br />
= 20kHz, 10kHz, 5kHz,2.5kHz) using gain <strong>of</strong> P controller designed<br />
for T<br />
s<br />
= 200µ s ( f<br />
s<br />
= 5kHz).<br />
After modification <strong>of</strong> P flux controller gain according to Table 5.1 it is possible to<br />
achieve better results as shown in Fig. 5.13, what confirms proper flux tracking<br />
performance in steady and dynamics state.<br />
