电动汽车电驱动系统瞬态扭振特性及主动抑制方法研究
Research on transient torsional vibration characteristics and active suppression methods of electric drive system for electric vehicle
摘要
Abstract
There are multiple nonlinear vibration excitation sources inside the electric drive system for electric vehicles.Among them,the system vibration is particularly prominent under transient impact conditions.With the consideration of the electromagnetic vibration of the motor,gear dynamic meshing and the operating characteristics of the electronic control system,an electro-mechanical coupling dynamics model of the EV drive system is built to study its electro-mechanical coupling dynamic behaviors of the electric drive system under such transient conditions as torque steps and load shocks.On this basis,a nonlinear active disturbance rejection controller is designed,taking the angular acceleration of the motor equal to zero as the tracking control objective.This transforms vibration suppression into a trajectory tracking problem an active suppression strategy for transient torsional vibration based on active disturbance rejection torque compensation.The vibration suppression performance of the proposed control method is further analyzed under sudden torque and load vibrations.Simulation results show active vibration control based on active disturbance rejection torque compensation effectively attenuates the external impact of the transmission system.Under rapid acceleration and load impact conditions,compared with the conventional control method,the peak angular acceleration of the drive motor is down by 50.82％and 40.43％while the convergence time of speed fluctuation is reduced by 54.26％and 44.85％respectively.关键词
