| 摘要: |
| 为改善混联式混合动力汽车动态响应过程中系统性能降低的问题，建立各个动力源系统的动态响应模型以及耦合机构模型，提出采用多动力源协调控制策略.电机A采用专家PID控制，发动机采用虚拟速差控制，电机B采用基于模型的补偿控制，利用系统特殊耦合关系，减小动态响应过程中各状态量相对于稳态优化点的波动程度.仿真结果表明，提出的协调控制策略使动态响应过程的时间缩短，发动机、电机以及输出轴的转矩转速波动减小.多动力源协调控制策略显著提高了动态响应过程中的系统性能.

| Abstract: |
| The relative slow responding speed of system Electro-mechanical system, which is caused by the inertia and response lag of the engine and motors, results that the target points optimized through the upper control strategy cannot be tracked quickly and precisely. A coordinate strategy for electro-mechanical system based on dynamic response models of power sources and the mechanical system is present. The expert PID control and Model compensation control are used on Motor A and Motor B respectively, besides the engine adapts the virtual speed difference control. Furthermore, the dynamic response of state parameters can follow the optimized-state points well. The simulation results indicate that the desired control characteristic of coordinate control strategy is validated and the torque and rotation speed fluctuations of the motors and engine decrease significantly.
