This paper presents a Simulink model of a car wheel slip control loop as might be used in a rudimentary ABS system. Although idealized equations are used, the overall model demonstrates many of the essential features of a Simulink model. Each of the individual components in the loop are discussed separately: a tire model; a quarter car model; a brake actuator; and a (PI) controller. The model for each component demonstrates a different feature of Simulink: the tire model shows how to implement a simple equation; the quarter car model shows how to implement non-linear continuous time equations; the actuator model illustrates how to handle time delays; while the controller shows how to implement discrete time difference equations. Since the quarter car model and actuator are modelled in continuous time, while the controller is implemented in discrete time, the developed model is also excellent example of how to implement hybrid continuousdiscrete systems within Simulink.
