| Abstract: | The delay-dependent stability criterion,the state observers design and observer-based stabilization are dealt with for linear neutral delay systems.Firstly,a delay-dependent stability criterion is developed based on a method of linear matrix inequality(LMI).Secondly,an LMI-based observer design for the error dynamics is presented.Thirdly,the observer-based stabilization problem of the neutral delay systems is solved by means of the solvability of two LMIs.Finally,two numerical examples are used to demonstrate the validity and effectiveness of the proposed approaches. |
