Adaptive observer design for LPV systems

摘要

In this paper, a design of an adaptive observer for linear parameter varying (LPV) systems is proposed. This observer must be able to estimate simultaneously states and parameters. The estimated parameter vector is used to compute the scheduling functions and thus interpolate the local linear models. Its conditions of existence and stability are given and its design is obtained in terms of a set of linear matrix inequalities (LMI). The efficiency of the proposed approach is illustrated by an academic example.
