Robust nested sliding mode integral control for anti-lock brake system

摘要

An integral nested Sliding Mode (SM) Block Control is proposed to control an Anti-lock Brake System (ABS) by employing integral SM and nested SM concepts. The control problem is to achieve reference tracking for the slip rate, such that, the friction between tyre and road surface is good enough to control the car. The closed-loop system is robust in presence of matched and unmatched perturbations.udTo show the performance of the proposed control strategy, a simulation study is carried on, where results show good behaviour of the ABS under variations in the road friction.
