This paper presents a new observer based fuzzy terminal sliding mode controller design for a class of fractional order nonlinear systems. Robustness against uncertainty and disturbance, the stability of the close loop system and the convergence of both the tracking and observer errors to zero are the merits of the proposed the observer and the controller. The high gain observer is applied to es...

We examine information nature of observing interactive processes during conversion of observed uncertainty to observer certainty, which leads to minimax information law of both optimal extraction and consumption of information: by getting maximum of information from each of its observed minimum and minimizing the maximum while spending it. The minimax is a dual complimentary variation principle...

This contribution presents a Lyapunov-based controller and observer design method to achieve an effective process for more dedicated closed-loop dynamics, i.e., maximal flexibility in observer-based with large consistency desired achieved system dynamics is intended. The proposed, pragmatic approach enhances the scope by using local instead of global Lyapunov functions, beneficial systems widel...

this study aimed to evaluate the reliability factors, and identify causes of error in direct anthropometry method. after training three beginner anthropometrists and following the instructions of anthropometric standards, 48 body dimensions of 42 male students were measured three times. in other words, the physical dimensions of each subject were measured for 9 times. all participants were wear...
