Extremum Seeking Control for Anti-Lock Braking Systems

Learn how to optimize braking torque for an anti-lock braking system to minimize stopping distance of a vehicle. Use the Extremum Seeking Controller block to maximize the friction coefficient characteristic between the road and the tire surface by optimizing the desired wheel slip. This block tracks the maximum of the friction coefficient characteristic function by modulating the desired wheel slip with sinusoidal signals, demodulating the resulting perturbed objective function, and updating the desired wheel slip by integrating the demodulated signal. Compare the braking performance of the vehicle with and without the anti-lock braking system under hard braking conditions.
