Célértéke

Célértéke is a Hungarian term that translates to “target value” or “desired value” in English. It denotes the value that a quantity, system, or model aims to achieve under given conditions. The term is used across disciplines to describe an ideal or reference point against which actual values are compared or toward which a process is steered.

In mathematics and optimization, the célértéke of a variable or function is the value that a solution should reach. Problems may define tolerances around the célértéke, or aim to minimize the deviation from it. In iterative algorithms, updating rules often move the current estimate closer to the célértéke.

In control theory and engineering, the target value is commonly referred to as the setpoint. The controller acts to drive the measured variable toward the célértéke, despite disturbances or uncertainties. In practice, the achieved value may differ from the target due to noise, delays, or nonideal dynamics, and the difference is evaluated as error or bias.

In metrology and calibration, the célértéke is the reference or true value used to assess measurement accuracy. Calibration procedures adjust instruments so that their readings align with the target value within specified tolerances.

Examples include setting a thermostat to a desired temperature, specifying a manufacturing dimension as the target value, or calibrating a sensor so that its output matches the established célértéke.
