Abstract :
The purpose of this paper is to provide new methods for neutral system stability and diagnosis analysis. Based on Kharitonov stability, a new theorem is proposed for delay neutral system with robust control. For stabilized neutral system, an unknown input observer with new structure is then investigated to diagnosis this type of system. Tow important conditions are presented to can apply this type of observer. Analysis of the simulation results reveals that the application of proposed theorem and approach provide a comprehensive result for fault neutral system stability and diagnosis.
