Fault diagnosis applied on the heat exchanger

Monitoring and diagnosis of complex systems is a challenging problem for designing real-time embedded system and has recently attracted considerable research effons. Thc papcr deals with thc faults dctection and identification by thc tool of timcd automata (TA). Advantage of final state automata with time consideration is in easy implementation into the PLC and systematic way of diagnostic design. The modelling task and diagnostic algorithms are overviewed and theory is applied on technological model of Heat Exehangcr. The application is detailed in different Ievel of implementation.
