Comparison of linear and nonlinear controller applied to an Antilock Braking System

Two control techniques are developed for a quarter of a vehicle ABS, Antilock Braking System, using a laboratory setup, manufactured by INTECO. A space-state mathematical model was obtained from the system. The first technique is a basic PID controller and the second one is a nonlinear control method through error feedback using Lyapunov function techniques. Finally, both controllers are simulated using the mathematical model and then compared.
