A class of systems influenced by nonlinearly parameterized perturbations is considered. An estimation scheme is developed whereby exponentially stable estimates of the unknown parameters can be obtained with an arbitrarily large region of attraction, provided the states are available for measurement. The method applies to a class of perturbations with the property that an exponentially stable e...

We remark that some stationary processes do not verify $x_\infty|x_\infty$ is equal to its value. To this, we propose a new definitions differentiate it in which process asymptotically stable if verifies this property. also all financial models have missed Which leads us reexamine the and look impact importance of

In this work, we address the adaptive control and synchronization problems of Chua’s circuits with unknown system parameters. Adaptive controllers with single state feedback are derived such that the trajectory of the Chua’s circuit is globally stabilized to an equilibrium point of the uncontrolled system. In addition, the proposed adaptive control schemes are then applied to achieve state sync...

In this paper, the problem of delay dependent robust asymptotically stable for uncertain linear time-variant system with multiple delays is investigated. A new delay-dependent stability sufficient condition is given by using the Lyapunov method, linear matrix inequality (LMI), parameterized first-order model transformation technique and transformation of the interval uncertainty in to the norm ...
