Abstract :
A new technique for estimating parameter drift, based on the method of potential functions, is suggested. When one of the parameters has a very much larger drift than the others, thus constituting a fault, it has been found possible to isolate this parameter as the one with the largest estimated drift, even though the sensitivity functions associated with the parameters are not orthogonal.
