models and vice versa was illustrated using the control system toolbox in Section 4.10. Simulink
provides a mechanism for incorporating state variable models of system components using the
‘‘State-Space’’ block located in the ‘‘Continuous’’ sublibrary. A partial description of
the ‘‘State-Space’’ block is shown in Figure 5.24. The next example illustrates its use.
Example 5.2
An automobile traveling along a level road at a constant speed v
0
encounters a speed bump
shown in Figure 5.25. The vehicle’s suspension system (front and rear springs and shock absorb-
ers) is modeled by linear springs and dampers, and the compliance of the tires is modeled
