Embodiment 1
[0123] The control object of this embodiment is the embedded permanent magnet synchronous motor 3 with a power of 1.5kW, a rated current of 3.9A, a rated voltage of 220V, and a rated speed of 5000r / min. The control chip is TMS320F28335, and the three-phase inverter 2 is PS22A74 intelligent power module IPM.
[0124] Applying the traditional control strategy to the above-mentioned embedded permanent magnet synchronous motor 3, the output waveform of the three-phase stator current is obtained, as shown in Figure 4 shown. Apply the optimized double-vector model predictive control method proposed in this application to the above-mentioned embedded permanent magnet synchronous motor 3, and obtain the three-phase stator current output waveform, such as Figure 5 shown.
[0125] by comparison Figure 4 and Figure 5 , it is found that the current pulsation of the traditional control strategy is large, and the proposed optimal dual-vector model predictive control method can effec...
