Abstract : "This paper is concerned with the problem of positive observer design for impulsive positive systems
(IPS) with interval uncertainties and time delay. A copositive Lyapunov-Krasovskii functional with exponential
term is constructed. By applying the average impulsive interval method, sufficient conditions for the existence of
the positive observer are established to guarantee the exponential stability of the corresponding augmented system,
which ensures the designed positive observer can estimate the system states exponentially. Combined with the linear
programming (LP) technique, an algorithm is developed to design the observer gain matrices. Finally, a numerical
example is provided to show the effectiveness of the theoretical results."
