The signals are modelled and their values must be found within the prescribed bounds. However, an abrupt change of the signal ncreases the estimated parameters’ variance, which raises uncertainty of the sensor condition although it operates correctly. This increase affects the whole system in evaluation of condition uncertainty. The solution must be fast and simple, because of runtime application requirements. The signal is modelled by a static model with uniform noise, variance increase is tested and if detected, the model memory is cleared. The fast and efficient algorithm is demonstrated on industrial rolling data. The method prevents the parameters’ variance from the artificial increase. cav_un_auth*0318350 12th International Conference on Informatics in Control, Automation and Robotics - ICINCO 2015 21.07.2015-23.07.2015 Colmar FR BC 2016 2 PO RVO:67985556 http://hdl.handle.net/11104/0248315 S 2015 84943513835 SCOPUS 000381618600081 WOS cav_un_epca*0446089 Proceedings of the 12th International Conference on Informatics in Control, Automation and Robotics Volume 1 1 978-989-758-122-9 603 607 Proceedings of the 12th International Conference on Informatics in Control, Automation and Robotics Portugal SCITEPRESS – Science and Technology Publications 2015 Filipe J. 340 Madani K. 340 Gusikhin O. 340 Sasiadek J. 340
