Abstract
Although a number of methods have been reported to design adaptive controllers for the plants described as linear time-invariant systems, a few as linear time-varying systems. However, these recent methods for time-varying plants require crucial design conditions on parameter varition of plants, dead-time, inverse stability, and their application to existing plants is restricted. This paper presents a new method to design adaptive controllers for linear time-varying plants, which does not require such conditions at all. It is such a general method as can be applied to the plants which others cannot and includes most of principal conventional ones as special cases.
