Control theory is concerned with maintaining some optimal state in a dy-
namical system. It works by obtaining feedback on its current state in an
environment, making a decision, and then issuing commands to take some
action. In a mechatronic device, control is typically managed by a

Mechatronic devices are widespread in many societies. A car, for in-
stance, combines mechanical systems with electrical systems and a central
computer. Many

state, such as its speed, fuel level and engine temperature. These signals are
transported by electrical pathways to the car’s computer, which makes deci-
sions on how to respond. If fuel is too low or the engine is too hot, the com-
puter may issue a command to display a warning message to the operator.
