Interval State Estimation of Systems with Metzler Polytopic Models
Author:
Abstract: The paper deals with the design of interval observers for interval-defined strictly Metzler polytopic
positive systems. The stability conditions for the proposed structure of the interval observer are formulated using
linear matrix inequalities to ensure a positive estimate of the system state. The proposed method makes it possible
to calculate time-varying lower and upper estimates of the state vector, assuming that the disturbance is bounded.
Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
