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 ...

Abstract The selection of input and output items is crucial for successful application Data Envelopment Analysis (DEA) as they should express the decision maker's preferences perceptions what might affect efficiency a making unit (DMU). This article addresses question transformation data that may be required analyses using DEA method. Different methods are available in literature, however, lead...

Memory properties of fractional-order operators are considered for an input-output data model highly uncertain nonlinear systems. The arises by relating the variation output to input; instantaneous gain is computed through a fuzzy inference network, whose consequences adapted online on gradient descent rule. nature proposed relaxes stringent conditions data-driven schemes, allowing changes in s...
