摘要：

为了提高增程器转速系统的响应速度和抗干扰能力，降低增程器的转速波动，提出了一种基于发电机转矩补偿的发动机转矩振动抑制方法。该方法首先分析发动机的输出转矩，确定转矩谐波成分对转速的影响，然后设计自适应反步法和重复控制器相结合的控制策略，其中重复控制器根据系统周期性转矩扰动的基频进行参数设计，并分析系统的稳定性和鲁棒性。最后，在不同工况下进行仿真实验，结果表明该控制策略在抑制增程器转速波动方面具有良好的有效性。

Abstract:

To enhance the system's response speed and anti-interference capability and reduce the speed fluctuations of the range extender， a method of using generator torque to compensate for engine torque vibration is peoposed. The output torque of the engine to determine the influence of the harmonic components in the torque on the speed is analyzed. Then， a control strategy combining an adaptive backstepping method and a repetitive controller is designed. The repetitive controller is parameterized based on the fundamental frequency of the periodic torque disturbance of the system， and the stability and robustness of the system are analyzed. Finally， simulation experiments are conducted under different operating conditions， and the results show that this control strategy has good effectiveness and practicability in suppressing the speed fluctuations of the range extender.

Key words: Vehicle engineering, control theory and control engineering, speed control, torque compensation, adaptive backstepping, repetitive control
