Review of Classical Control
A “system” is a collection of “components” which interact with one another and with their “environment.” A very good example of a system is a political system such as the United States containing many components, its 50 states, which interact with not only each other but also neighboring countries. A “control” system, which can be either “open-loop” or “closed-loop,” is a collection of components that interact in such a way that a particular “input” results in a particular “output.” Otherwise, it is out of control. A “deterministic” control system is one where the input/output relationship is predictable and repeatable. Otherwise, it is stochastic. For example, an electromechanical system such as the DC motor is a deterministic control system that contains many components: resistor, inductor, magnetic coupling, inertia, viscous damper, etc.; their interaction is such that a specific input voltage will result in a specific output velocity.
