Research on Electric Vehicle Clutch Slip Control Considering Time-Varying Disturbance
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.
