Gain scheduling using the Youla parameterization

Abstract

Gain scheduling controllers are considered in this paper. The gain scheduling problem where the scheduling parameter vector cannot be measured directly, but needs to be estimated is considered. An estimation of the scheduling vector has been derived by using the Youla parameterization. The use of the Youla parameterization in connection with estimation of directly gives a validation method for the estimate of . The validation part is an integrated part of the estimation method. This will make it possible to estimate the parameter vector very precisely. This is important in connection with H1 gain scheduling controllers
