| Description
| - Postupná ztráta kredibility senzorů měřicích regulované veličiny v regulačních obvodech (tzv. diskredibilita senzorů regulačního obvodu) může způsobit při regulaci vážné, obtížně detekovatelné problémy. Pokud senzor poskytuje zkreslené údaje, které nejsou správné, ale také nejsou zcela špatné, vzniká nebezpečí vzniku nežádoucích vedlejší efektů, které zůstanou nerozpoznány. Tento problém se stává závažný zejména u spalovacích procesů. V případě pilotního tepelného roštového kotle, který je k dispozici pro experimenty v laboratořích ČVUT v Praze, je problém diskredibility senzoru spojen s funkcí kyslíkové sondy použité pro přesnou regulaci spalovacího vzduchu. Diskredibilita kyslíkové sondy je velmi obtížně odhalitelná, protože hlavní (tepelný) regulační obvod pracuje bez jakýchkoliv problémů. Obvyklý způsob detekce diskredibility je použit více měřicích zařízení. V příspěvku je ukázáno porovnání softwarových modelových metod s pomocí evolučních algoritmů. (cs)
- 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.
