Multiple sliding surface controller based on disturbance observer for anti-lock braking system

This paper is concerned about the wheel slip measurement of the anti-lock braking system (ABS). The wheel slip must follow the desired wheel slip; for this purpose multiple sliding surface controller (MSSC) based on disturbance observer (DO) is used. DO is integrated with sliding mode controller (SMC) to strengthen the overall performance of the system by estimating the lumped uncertainties that are present in the system. The performance of the suggested scheme is testified in MATLAB/simulink with experimental set up of ABS by considering different cases for tracking the slip ratio.
