Abstract | The invention discloses a control method of a bidirectional DC/DC converter in a permanent magnet synchronous motor system, and relates to the field of permanent magnet synchronous motor systems, the method adopts double-loop cascade combination with feed-forward load current and adds a variable proportion link, an outer voltage loop is improved to an output capacitance current given value, and the output capacitance current given value is improved to the maximum value; the control method has the advantage of fast response to load change due to the fact that the bus current given value contains the load current, the inductive current given value is obtained based on the bus current given value in combination with a variable proportion link, and the control method is high in reliability and high in reliability. The control method has the advantages that the bus voltage can be quickly adjusted, the robustness on the parameter change of the bidirectional DC/DC converter can be realized, and the control performan |
