摘要：

The problem of interval observer design for systems described by linear models under the external disturbances is considered. The problem is solved based on the reduced-order model of the original system of minimal dimension. The relations allowing designing interval observer insensitive or having minimal sensitivity to the disturbance are obtained. The designed interval observers are used to solve the problem of fault diagnosis. Theoretical results are illustrated by example. Copyright (C) 2024 The Authors.
