This letter develops a new direct adaptive control framework that extends the certainty equivalence principle to general nonlinear systems with unmatched model uncertainties. The approach adjusts rate of adaptation online eliminate effects parameter estimation transients on stability. method can be immediately combined previously designed or learned feedback policy if corresponding model-parame...

There are a large number of dynamic objects, for the management which it is advisable to apply principles adaptation. The reasons applying adaptation can be combined into two main groups: variability and complexity characteristics objects environment; growing requirements accuracy technical economic systems. difference between adaptive systems optimal ones that while in quality indicator provid...

the long term goal attaining of economic system management requires the establishment of a dynamic framework to integrate multiple perspectives. this article considers the problem of economic development in macro level. as economic systems are complex adaptive systems composed of numerous numbers of components of dynamic and multidimensional nature, dynamics method is applied in this research. ...
