Question: what are control systems ?

Joseph Chilcott answered on 11 Mar 2015:

Good question. a control system is a system that aims to maintain a specified state. For example, the thermostat in a house maintains the a specified temperature by warming radiators, measuring the temperature of the house and comparing it to the temperature that was specified by the user.

Another example if if you take a person balancing on a beam of wood. Their body is acting as a control system by calculated which way the person needs to lean to maintain their balance and not fall off a beam

Does that answer your question?
