摘　　要：设计了由转速、电流双闭环构成的电传动控制系统,使驱动电动机的输出功率与发动机输出功率相匹配,保证发动机能按其经济特性运行。起动时保持恒定最大允许电流,在尽可能短的时间内增加转速,使车辆具有良好的起动性能。在车辆行驶中保持系统的恒定输出,克服行驶阻力突然变化等扰动的影响。运用Matlab进行了仿真,得到了良好的静、动态品质。An electric drive truck control system composed with a speed-current dual loop was designed to ensure the output power of electromotor and engine were matched and the engine can operate in economical condition. This demand the engine keep maximum permit current and accelerate in the shortest time to keep the vehicle＇s best startup capability. Changeless output of vehicle in operation was guaranteed and impact like change when overcoming resistance during driving was overcame. Simulation result with Matlab provide the static and dynamic characteristic of the system.
