Název v původním jazyce

Improvement of Control Loop Function by Control Variable Sensor Discredibility Detection

Popis výsledku v původním jazyce

The gradual loss of the credibility of sensors measuring control variables in control loops (so-called control variable sensor discredibility) may cause serious difficulty detectable problems in control. If such a sensor produces biased data, which are not correct but not totally wrong, then there is a danger that undesirable side effects may occur and they remain unrecognized. This problem becomes important especially in combustion processes. In case of a pilot stoke-fired boiler, which has been used for experiments in the CTU labs, the sensor discredibility problem is related with function of the oxygen probe used for accurate control of the burning air. The discredibility of the oxygen probe is very difficult to reveal because the main (temperature)control loop seems to be working without any problems. The usual way of discredibility detection is to use more measuring equipments. In this paper, a comparison of software evolutionary model-based methods is shown.
