摘要
针对电动汽车离合器系统中存在的时变扰动,提出了新型逆自动机械变速器超越离合器,并设计了基于高阶扰动观测器的离合器最优控制方案.该控制器通过哈密顿方法引入新的乘子函数λ,并以系统状态、扰动和扰动导数的反馈形式给出了最优控制律,然后将该控制器应用于配备逆自动机械变速器的电动汽车换挡时的离合器滑移过程.最后通过仿真表明,该控制器在不同的工作场景和不同的干扰条件下都能保证系统的一致性,保证了离合器滑移过程的平稳性,提高了电动汽车的整体换挡质量.
Abstract
Aiming at the time-varying disturbances in the clutch system of electric vehicles,a novel inverse automatic mechanical transmission overrunning clutch is proposed,and an optimal clutch control scheme based on a high-order disturbance observer is designed.The controller introduces a new multiplier function λ through the Hamiltonian method,and gives the optimal control law in the form of feedback of the system state,disturbance and the derivative of the disturbance,and then the controller is applied to an electric vehicle equipped with an inverse automatic mechanical transmission Clutch slippage when shifting gears.Finally,the simulation shows that the controller can ensure the consistency of the system under different working scenarios and different in-terference conditions,ensure the stability of the clutch slip process,and improve the overall shifting quality of the electric vehicle.
