Generally it is said that a fuzzy control system has fault tolerant properties, but it is not clearly studied. In this paper, first, the influence of faults in fuzzy control systems is examined. Errors given by fault simulation are not negligible. However, no fault detecting method is applied in the realized fuzzy control systems. Then a fault-checking method to detect faults is proposed in this paper.
