Build a Hybrid Model

2-31

• ABS Controller subsystem that accepts a setpoint from the Desired Relative Slip

block and provides a control signal to the braking system.

• Brake System Dynamics subsystem that models the behavior of an actual braking

system.

• Sensor Relative Slip subsystem that feeds a measured slip value back to the ABS

Controller block.

Simulate the braking system. In the Simulink Editor, select Simulation > Run.

The scope outputs show:

• The change in wheel speed versus the decreasing speed of the vehicle. The plot shows

that the wheel speed stays below the vehicle speed without locking up (suddenly

decreasing towards zero), with vehicle speed going to zero in less than 15 seconds.

• The slip response of the braking system relative to the Desired setpoint. Throughout

the simulation, the error between the desired slip value and the measured slip value

remains small.
