Abstract

This paper proposes a fault detection scheme of examining if a human operator is in good condition when the operator handles a switching system. We model a switching system driven by on-off manipulations of an operator. It is expressed by a sequence of the continuous variables sampled at the instant that on-off manipulations are applied to the system. Then, we detect a human error which occurs when an operator is engaged in on-off manipulations using statistical hypotheses testing.
