In the control, a value is predetermined and the end.

In the control, it is checked whether the desired value has been reached and, if necessary, the control is corrected by feedback until the desired value is reached.

In this respect, for example, the common “loud strength controller” on the radio is NO controller, but a controller. Only when you involve the person who still isn’t loud enough and who then adjusts the volume, is a regulation from it.

Similar to car driving. They say the driver controls the car… In fact, he uses the control. It turns the control to the left and the car goes to the left. If the driver notices that it was too much or too little left he corrected after… at this moment, taking into account the review of the result (too much or too little left) and corresponding influence on the steering wheel (more or less steering impact) a regulation of this.

A control therefore only sets a value. A regulation also checks (more or less regularly) whether the value has also been reached and “regulates” if necessary.

The control has an open action sequence, i.e. there is no feedback. This sequence of effects is called a control chain. Control → closed course of action: The control has a closed sequence of effects, i.e. a feedback takes place between system 1 and system 2 .

Imagine you want to have a room temperature of 20° degrees. However, the instantaneous temperature is, for example, 0°. A controller has the task of bringing the room temperature from 0° to 20°. If everything goes smoothly and doesn’t work, you’re done. In reality, not everything is ideal and the control only brings the room temperature close to the desired value. From there, the regulation comes into play. A linear control only works if you are already close to the working point. It regulates the remaining deviation.
