Direct Torque Control with Space Vector Modulation The behavior of the torque control loop was tested using SABER simulation package. The model created in SABER takes into account the whole control system, which include real models of inverter and permanent magnet synchronous motor. The torque step response is shown in Fig. 5.44, when parameters of PI torque controller designed for sampling time T s = 200µ s were used for control plant for different sampling times T s = 50µ s , 100µ s , 200µ s , 400µ s , which correspond to switching frequency f s = 20kHz, 10kHz, 5kHz, 2.5kHz. Figure 5.44. Torque tracking performance for different sampling time T s = 50µ s , 100µ s , 200µ s , 400µ s ( f s = 20kHz, 10kHz, 5kHz,2.5kHz) using parameters of PI controller designed for T s = 200µ s ( f s = 5kHz). Pleas note that for 2.5kHz the system was unstable. After modification of PI flux controller parameters according to Table 5.4 it is possible to achieve better results as shown in Fig. 5.45, what confirms proper torque tracking performance in steady and dynamics state. 108
