Selvkalibrering

Selvkalibrering, often translated as self-calibration, refers to a process where a system or device automatically adjusts its internal parameters to ensure accurate measurements or performance without external intervention. This is particularly relevant in fields like metrology, control systems, and sensor technology. The core idea is that the system uses its own outputs or internal references to correct for drift, aging, or other sources of error.

One common application is in measuring instruments. A self-calibrating instrument might periodically perform a check against a known internal standard or analyze the stability of its own zero point. If a deviation is detected beyond a certain threshold, the system automatically updates its calibration data, thereby maintaining accuracy. This reduces the need for frequent manual recalibration, which can be time-consuming and costly.

In control systems, self-calibration can be used to adapt to changing environmental conditions or component degradation. For example, a robotic arm might self-calibrate its joint positions to compensate for temperature-induced expansion or wear. Similarly, in communication systems, self-calibration can adjust signal processing parameters to optimize performance in a dynamic environment. The implementation of self-calibration typically involves algorithms that monitor system behavior and initiate corrective actions when deviations from expected performance are observed. This automation enhances reliability and reduces the burden on operators.
