考虑轮胎滑移特性的功率分流混合动力系统模式切换扭振控制
Research on mode switching torsional vibration control of power-split hybrid electric system considering tire slip
摘要
Abstract
The power-split hybrid electric system is susceptible to low-frequency torsional vibration during clutch state transitions and power source torque fluctuations.In particular,the nonlinear friction behavior of tire slip introduces damping into the drivetrain,altering the torsional vibration characteristics during mode switching.This paper employs a lever-based modeling approach,integrating a nonlinear tire model to investigate the torsional vibration dynamics of mode switching under varied road adhesion conditions,with a focus on tire slip behavior.To meet the requirements for high-quality mode switching across different road surfaces,the uncertainty of road adhesion is characterized as bounded uncertainty.An adaptive non-singular fast terminal sliding mode controller(ANFTSMC)is proposed to effectively address the disturbances caused by tire slip parameter variations and external influences.Simulation results demonstrate the proposed control strategy markedly reduces the maximum jerk during mode switching on both asphalt and icy road surfaces.Moreover,it cuts the mode switching time and exhibits enhanced adaptive capabilities,leading to a notable improvement in overall vehicle mode switching quality under varied road adhesion conditions.关键词
