In a control system, the term "set point" refers to:

The term "set point" in a control system specifically denotes the desired output level that a system aims to achieve or maintain during operation. This is the target value that the control system strives to reach. For example, in a temperature control system, if the desired temperature is set to 70 degrees Fahrenheit, then 70 degrees is the set point.

The control system then continuously monitors the actual measured value (such as the current temperature) and applies the necessary adjustments to ensure that the output aligns with this set point. This relationship between the set point and the actual measurement is fundamental in closed-loop control systems, enabling them to perform effectively by maintaining the necessary conditions as defined by the user or process requirements.

Other terms such as "actual measured value," "range of operation," and "calibration point" refer to different aspects of the control system but do not define what a set point is. The actual measured value is what the system reads in real-time, the range of operation defines the limits within which the system can function, and the calibration point is related to the accuracy of the sensors involved, not to the desired level itself.
