Comparative Analysis of Gain-Scheduled Wheel Slip Reset Controllers with Different Reset Strategies in Automotive Brake Systems

摘要

Wheel slip control bases its effectiveness on operating in the maximum adherence zone, guaranteeing the correct handling of the vehicle. The use of brake-by-wire systems and electromechanical actuators, make possible the control of each wheel slip independently, improving the performance of braking systems. Several controllers are proposed to enhance the overall effectiveness of the braking maneuver. To do this, several reset strategies are compared: reset control with zero crossing, fixed reset band and variable reset band. The improvements achieved proceed from the betterment of the outputs of the system such as the transient time and the overshooting. The robustness of the system to changes in the friction conditions is also improved by reset control and reset bands.
