THE ANTI LOCK BRAKE SYSTEM MODEL WITH WHEEL SPEED,VEHICLE SPEED AND SLIP RATIO MATLAB. Simulink are used to develop and simulate the controllers. Then, Simulink Coder, and Real-Time Windows Target are used to generate and run the resulting controllers in real time on the physical ABS system. The ABS model is the perfect tool for research and teaching at technical universities in the field of automatic control and mechatronic systems.
