As the physical systems we model become progressively more complex, the Simulink representation increases in size, that is, the number of blocks required to model the systems’ dynamics grows significantly. A Simulink diagram with hundreds of blocks makes it difficult, if not impossible, to understand the interactions among the systems’ components. A more instructive approach consists of grouping specific blocks associated with various subsystems into single entities. At the highest level, the system is viewed in terms of the interactions between these entities.
This hierarchical approach is illustrated for the case of modeling the dynamics of an automobile. Figure 5.58 shows a block diagram of the top level description for modeling ...
