Why Interconnect Models?

Interconnecting models of components allows you to construct models of control systems. You can conceptualize your control system as a block diagram containing multiple interconnected components, such as a plant or a controller. Using model arithmetic or interconnection commands, you combine models of each of these components into a single model representing the entire block diagram.

For example, you can interconnect dynamic system models of a plant G(s), a controller C(s), sensor dynamics S(s), and a filter F(s) to construct a single model that represents the entire closed-loop control system in the following illustration:
