RT Journal Article SR Electronic A1 Spalek, Juraj A1 Molnarova, Monika T1 Using Fuzzy Logic in the Critical Process Controlling JF Communications - Scientific Letters of the University of Zilina YR 1999 VO 1 IS 1 SP 13 OP 17 DO 10.26552/com.C.1999.1.13-17 UL https://komunikacie.uniza.sk/artkey/csl-199901-0002.php AB In this paper the advantages of fuzzy logic used for two - channel systems output comparison in safety - related critical applications have been presented. The paper deals with the design of the fuzzy logic - based comparator that compares the data of traction vehicle velocity in target braking process and its optimisation using the ANFIS method. Some failures of the system in Matlab - Simulink environment have been simulated. The result is the analysis of ailures consequences from the point of system safety.
