Abstract
The present disclosure relates to a system and a method for validating the validity of a sensor, in particular, validating the validity of a sensor using a control limit. The method for validating the validity of a sensor using a control limit includes inferring a posterior distribution of a parameter in a Bayesian technique using a prior distribution of the parameter of sensor data and historical data of the sensor, setting a target credible interval for the posterior distribution of the parameter and setting a control line of the sensor data using the set credible interval, and validating the validity of the sensor by monitoring whether the actual measurement data of the sensor deviates from the control line.
