Use runs tests for process control

The article is devoted to adaptation criterion series for use in process control algorithms. Criterion series is proposed for detecting abrupt changes in trend information and diagnostics of device. The use of this criterion is justified on the programmable logic controllers of small and medium power. The air temperature control system which has a variety of sources of information is regarded as the object. The object has non-linear properties, which complicates the analysis. The standard algorithms filtration was implemented in the programmable logic controller. The data were recorded and processed with MatLAB. The estimation of noise that affects the sensors thermal object was carried out. The criterion settings should be selected taking into account the dynamics of the object and the sensor. Quality filtration and static errors affect the accuracy of the method. Speed of the modern programmable logic controllers allows using a small length of the series or multiple series.
