Research on Matching of Motor Control System Based on Electric Drive of Engineering Vehicle

In this paper, on the basis of the control research of a single inverter controlling dual motors in the power batterypowered mode for the scenario of parallel motor application in engineering vehicles, the mathematical model applied to electric drive motor control was derived, the motor stator parallel current control strategy was analyzed, and the research of energy-saving operation strategy based on bus-type topology was innovatively proposed. The research equipment was used to develop a reference correlation between the wheelside speed parameter K and the average rotor magnetic field directional parallel control method under loose pavement wheelside slip rotation conditions. In order to improve the starting performance of parallel motors under unbalanced load and reduce the unbalanced degree of parallel motor speed, this experiment applied a parallel control strategy based on weighted vector based on the average rotor magnetic field orientation control. The results show that the machine intelligence level was improved and the energy saving effect of reducing the heat loss of the motor was achieved.
