Abstract For the engine speed control in a range extender, responsiveness and anti-disturbance ability of the engine speed system are limited due to the inherent delay and slow response of the engine torque. In order to improve the system performance, a speed control strategy is proposed with the generator torque as an auxiliary input besides the engine torque. Firstly, an engine load compensation is presented to decouple the response from the required generator torque to the engine speed. In addition, a parameterization controller with an anti-windup strategy is provided to control the engine speed; the robustness and stability of the system are also analyzed. Then the undesired open-loop pole of the system is reconfigured using the generator torque as a secondary input to improve the anti-disturbance performance of the system. And the actual generator torque is designed to converge to the required torque when the engine is stable at the required speed to satisfy the power requirement of the vehicle. The effectiveness and practicability of the proposed strategy are evaluated by simulations on Matlab/Simulink and experiments on a range extender.

以发电机转矩为辅助输入的增程发动机转速控制策略
摘要 对于增程器中的发动机转速控制,由于发动机扭矩固有的延迟和响应缓慢,使得发动机转速系统的响应能力和抗干扰能力受到限制。为了提高系统性能,提出了除发动机扭矩外,以发电机扭矩作为辅助输入的速度控制策略。首先,提出了发动机负载补偿,以将响应从所需的发电机扭矩到发动机速度解耦。此外,提供具有抗饱和策略的参数化控制器来控制发动机转速;还分析了系统的鲁棒性和稳定性。然后使用发电机转矩作为辅助输入重新配置系统的非期望开环极点,以提高系统的抗干扰性能。并且当发动机稳定在所需速度以满足车辆的功率需求时,实际发电机扭矩被设计为收敛到所需扭矩。通过在 Matlab/Simulink 上的模拟和在增程器上的实验来评估所提出策略的有效性和实用性。
