Abstract

Interval estimation design for a class of parametric varying systems is considered. Interval state observer for nonlinear system with varying parameters and constant time delay is proposed. Also we consider the case with unknown unmeasured perturbations and check the behavior of the interval estimates into simulations. The efficiency of this method is shown through computer modelling of a hormone testosterone dynamics system in the presence of time delay and disturbances.
