ABS control using optimum search via sliding modes

The paper presents the control design for antilock braking systems via the sliding mode approach. In this study we formulate the problem as that of extremum searching in a highly uncertain situation. We consider the friction force as an output of the dynamic system which includes mechanical motion equations and the hydraulic circuit equations. This setting is complicated by the optimized function being a priori unknown, and the input (slip) not being measurable.<<ETX>>
