摘要:  根据模型参考控制(MRC)的思路,针对混联式混合动力汽车由纯电动机驱动至发动机电动机共同驱动的模式切换过程,建立了混合动力传动系统动力学模型,以纯电动机驱动作为参考模型,推导稳定条件,选择前馈和反馈控制参数,实现转矩稳定过渡,避免剧烈冲击.研究表明,与传统的快速切换方法相比,MRC既能降低冲击度,又能减少滑摩功耗.并应用敏感性分析给出了前馈参数、转矩干扰和惯量比对控制品质的影响.

Abstract:   A model reference control (MRC) is proposed for the transition from motoronly driving mode to compound driving mode of a seriesparallel hybrid electric vehicle. The dynamics of the motoronly mode is regarded as the reference model. The stability condition is derived, and the control parameters are selected so as to guarantee the torque continuity which avoids intensive jerk. The results show that the MRC not only reduces vehicle jerk but also reduces frictional loss compared with the conventional method. Sensitivity analysis examines the influences of control parameters, actuation noise and ratio of inertia moment on the control quality.
