regulator

A regulator is a device that ensures that a given system works automatically and operates within the required range of values. A controlled system can be, for example, an engine, an electric motor, heating, air conditioning, a chemical process, etc.

The monitored parameter is read by the sensor and the controller calculates the control intervention to adjust this parameter to the desired value.

The regulator is designed so that after a certain time the regulation deviation is zero (or very small).

Regulation deviation - represents the difference between the desired value of the regulated parameter and its measured value.
Feedback - Feedback occurs when the input to a system is affected by its output. Feedback can be positive or negative. Negative feedback is when Y(s) subtracts from S(s).
Control intervention - is a value or vector of values that the controller calculates and sends to the system (for example, control voltage, valve opening, etc.).
Desired value – the value that the controlled parameter should reach, e.g. room temperature
Control to the desired value - it is suitable if we often change the desired value
Fault management - if the desired value is not changed for a long time, but faults occur in the system.
