摘要
针对电机一减速器/差速器式驱动系统的某电动车存在的喘振问题,分析驱动系统结构,建立驱动系统扭转振动数学模型并分析其振动特性;然后基于数学模型的分析设计了前馈一反馈扭转振动控制器,其中前馈环节可以改善电机突变转矩引起的电动车喘振,反馈环节可以消除扰动转矩引起的喘振。仿真结果表明,前馈一反馈控制方案可以有效改善电动车的喘振问题。
As for the surge problems existed in motor-reducer/differential drive system for an electric vehicle, analyzed the structure of drive system and established the mathematical model Lo analyzed the vibration characteris- tics. Based on the analysis of the mathematical model, designed a feed forward-feedback torsional vibration control- ler, in which the feed forward part can control the surge caused by motor torque step and the feedback part can con- trol the surge caused by disturbance. The simulation showed that the feed forward-feedback control can solve the surge problem effectively.
