| 摘要: |
| 为提高重型车辆用功率分流式混合动力系统机电功率流调控精度,解决外界用电需求的动态控制问题，提出电功率协调控制策略. 该策略利用电机快速响应和精确控制的特点，通过对发电机和电动机的闭环协调控制，调整二者的工作状态，保证动力源功率分配的精确性以及对外供电的稳定性. 仿真结果表明，提出的协调控制策略能够使电池实际功率时刻跟随其目标值，并且在外界有用电需求时，确保系统快速调整出相应的电功率以供使用，较好地解决了机电复合传动系统机电功率分配的精确性问题以及对外供电功率响应的复杂动态控制问题.

| Abstract: |
| The dual-mode electro-mechanical transmission system for heavy duty vehicles is a power split hybrid system, which transmits engine power through mechanical and electrical power flow. Aiming at the precision of mechanical and electrical power distribution and the responding speed of electrical power supply, the electric power coordinated control strategy is proposed. Making use of quick response and accuracy control of motors, the strategy can realize the precise power distribution of engine and battery and supply steady electric power by coordinating the working state of generator and motor. The simulation results indicate that the actual power of battery will follow its target value in real time and the electric power will be supplied rapidly when it is needed. The electric power coordinated control strategy can achieve the precise distribution of mechanical and electrical power and the high responding speed of electrical power supply in complex dynamic control system.
