Abstract

The problem of reduced-order observers design for linear neutral delay systems is investigated. Sufficient conditions for the existence of these observers are given. First, the general case is presented, then under more restrictive conditions a simple design method is developed for some special cases. Based on linear matrix inequality (LMI) and linear matrix equality (LME) formulation, independent of delays stability criteria are derived. A systematic design method of these observers is presented.
