Let’s say we live in a country that gets very cold, in Northern America / Europe. In winter, we monitor the ouside temperature, so that heaters can be switched on, inside the house. The idea is that, the colder it is outside, the warmer it should be inside. The heating side of things is just a heater that is either switched on, or switched off. Just from the information that has been given, please discuss this matter in depth. Provide reference to OPEN / CLOSED loop control, FEEDFORWARD / FEEDBACK control and MODULATING / ON_OFF control raised in the discussion.
