摘　　要：为解决电驱动拖拉机在田间工作有功率突变导致发动机实际转速不能立即达到需求转速的问题,设计两种基于转速的功率控制策略。经仿真试验,得出两种策略下功率阶跃增加时发动机工作状态和不同负载时的母线电压。进行比较分析,基于节约能源的考虑,选择策略一作为功率平衡控制策略。该控制策略提高能源利用率,为电驱动拖拉机控制策略完善的研究奠定基础。In order to solve the problem that electric drive tractor has the power mutation in the field work so that the actual engine speed can＇t reach the demand immediately,two speed based power control strategies are designed.Through the simulation test,the engine working status of power step increases and the bus voltage of the different load under the two strategies are concluded.After comparison and analysis,select the strategy one as the power balance control strategy,which based on considerations of energy conservation.The control strategy improves the energy efficiency of electric tractor the study of control strategy is perfect.The control strategy improves the energy utilization,and lays the foundation for the improvement of the control strategy of the electric drive tractor.
