Abstract :
A sliding mode based extremum seeking algorithm is applied to the ABS control problem where the optimum slip ratio is searched online for maximum braking force in unknown road conditions. By making the parameter of the search algorithm adaptive, an adaptive extremum seeking scheme is proposed to improve the behavior of the controlled system around the optimum operating point. Simulation study is presented to illustrate the effectiveness of the methodology.
