According to O. JOHANSEN BERTOGLIO (1985, p.184-85) a control system includes five basic parts:
a) a variable: this is the element (or programed goal) that must be controlled. Let us say a car's velocity
b) sensors: or mechanisms or devices able to perceive the variable's fluctuations. In the car's velocity case, we need a velocimeter, our visual capacity and our brain's interpretative capacity
c) motors: or effectors, able to develop corrective action. In this case, they include neurons, nerves and our muscular system to move our foot to accelerate or brake
d) an energy source: needed for any kind of activity. We need our stored physical energy and also, the energy that moves the motor
e) feedbacks: which, by communication of the variable's state registered by the sensors, trigger the corrective action. In this case they are the decisions made by our brain.
