• Abstract:

  SVPWM dual closed-loop current control parameter optimization methods usually rely on empirical formulas or trial-and-error methods to adjust the parameters of the current and voltage loops, which leads to poor optimization results due to the neglect of the effect of switching losses. In this regard, the optimization study of SVPWM dual closed-loop current control parameters is proposed. The comprehensive objective function of parameter optimization is constructed by comprehensively considering the indicators of harmonic distortion, DC bus utilization, switching loss and dynamic response. The boundaries of the control parameters are constrained by considering the current, voltage, switching frequency and parameter range. Finally, combined with the whale optimization algorithm, the optimal parameter combinations are solved by simulating the social behavior and search strategy of the whale during the feeding process, so as to realize the optimization of SVPWM dual closed-loop current control parameters. In the experiments, the optimization effect of the proposed method is verified. It is clear from the test and comparison results that when the proposed method is used for control parameter optimization, the average value of DC bus utilization is above 80%, which has a more ideal optimization effect .
