Pressure tracking of brake-by-wire system with parameters-predicted backstepping control

In this paper, a hybrid control algorithm is designed based on a motor-assisted hydraulic braking system that combines backstepping control with model predictive control. In designing the backstepping control strategy, the stepping parameters designed based on the Lyapunov stabilization method are further solved using model predictive control. The stepping parameters are optimized online on the basis of rolling. The control algorithm is applied to the constructed electro-hydraulic line control system model, and the feasibility of the hybrid algorithm is verified in pressure tracking simulation experiments.
