In this paper a novel method is proposed for construction of an exponential observer for nonlinear system. The presented method is based on direct solution of dynamic error without any linearzing of nonlinear terms. Necessary and sufficient conditions for construction of direct observer are presented. Stability of the observer is checked using Lyapunov theorem. Also the ability of this observer...

background among all pediatric cancers acute lymphoblastic leukemia (all) is highly prevalent, butthe overall cost of all management is not well-known, there is a need to assess the berlin-frankfurt-munster (bfm) protocol commonly used in all management in iran. so, the aim of this study was to estimate direct and indirect costs of all treatment among children based on the all-bfm protocol from...

The objective of this study is to design a robust direct model reference adaptive controller (DMRAC) for a nonlinear cardiovascular model over a range of plant parameters representing a variety of physical conditions. The direct adaptive controllers used in thisd study require the plant to be almost strictly positive real (ASPR) that is, for a plant to be controlled there must exist a feedback ...
