摘要：For a class of time-delay discrete-time linear systems with external disturbance and measurement noise,the interval estimation problems of state and measurement noise are investigated in this paper.First,the system state together with the time-delay term and measurement noise is augmented as a new state,and a singular system is then constructed.Subsequently,a kind of decoupling technique is employed to eliminate the effect of external disturbance,and an observer is designed to simultaneously estimate the system state and measurement noise.Based on the estimated state and measurement noise,the interval estimations of system state and measurement noise are obtained by reachability analysis technique.Finally,the effectiveness of the proposed method is verified by a four-tank liquid level system.
