An Observer-Based Finite Control Set Model Predictive Control for Three-Phase Power Converters

Figure 10

Waveforms of the currents and (3.0 A/div) with different startup sequence of the observers. (a) Filter time delay observer starts first, then the inductance observer starts (①: filter time delay observer starts; ②: the estimated values of filter time delay observer are passed to the current prediction of FCS-MPC; and ③: the inductance observer starts and passes its estimated value to the current prediction of FCS-MPC). (b) Inductance observer starts first, and then the filter time delay observer starts (①: the inductance observer starts and passes its estimated value to the current prediction of FCS-MPC; ②: filter time delay observer starts; and ③: the estimated values of filter time delay observer are passed to the current prediction of FCS-MPC).
