Abstract:In order to achieve fast and stable control of vehicle braking process,an explicit nonlinear model predictive controller for electrohydraulic antilock braking system was designed.Through the analysis of the electrohydraulic antilock braking system,its working process was clarified.On the basis of considering the system parameters,an explicit nonlinear model prediction controller was designed.The controller was integrated into the electrohydraulic antilock braking control system to calculate the adjusting torque.At the same time,the state predictor and buffer were used to compensate the dead time of the electrohydraulic antilock braking system,so as to improve the efficiency and stability of the braking process and solve the nonlinear optimal control problem of the electrohydraulic antilock braking system.The experimental results show that compared with the logic threshold control method,the explicit nonlinear model predictive controller has better realtime performance and better stability for vehicle braking control.
