摘要：

在对混合动力汽车启停运行机理分析的基础上,建立了能够反映启停过程的发动机瞬态动力学特性的AMESim仿真模型;然后,根据发动机启停系统工作原理,将混合动力汽车的启停控制问题转换成转速跟踪控制问题,并推导了简化的面向控制的电机与发动机系统耦合模型;针对系统的非线性特性,设计了非线性三步法启停控制器,并通过输入到状态稳定理论证明了闭环系统的鲁棒稳定性。最后,通过AMEsim和MATLAB/Simulink联合仿真验证了非线性三步法启停控制器的有效性和鲁棒性,实现了混合动力汽车的快速、平稳启停。

Abstract:

First,the start-stop operation mechanism of hybrid vehicle is analyzed, and an AMESim simulation model is established, which can reflect the transient dynamics of the start-stop process. Second, according to the working principle of the engine start-stop system, the start-stop control problem is described as a speed tracking problem, and a simplified control-oriented model of the engine and motor coupling is proposed. Third, based on the nonlinear characteristics of the system, a nonlinear triple-step controller is designed, and the robust stability of the closed-loop system is analyzed using the input to state stability theory. Finally, the effectiveness and robustness of the triple-step controller is tested by co-simulation with AMESim and MATLAB/Simulink. Results show that the proposed control system can achieve fast and smooth start-stop of the engine.

Key words: automatic control technology, vehicle engineering, start-stop control, hybrid electric vehicle, nonlinear triple-step, robustness
