Abstract

MUCH OF THE LITERATURE in the field of feedback control has been concerned with linear, time-invariant systems. The labor involved in obtaining solutions to even simple problems in time-varying systems may well have discouraged research in this area. Nevertheless, many practical systems unavoidably contain time-varying components, and methods of dealing with such systems are desirable.
