Abstract: This paper develops a theoretical basis and a systematic process for resolving all inertia forces along generalized coordinates from the overall energy equation of a dynamical system. The theory is developed for natural ...

Abstract: In this paper, we present an observer design for online estimation of species concentrations in recirculationbased solid oxide fuel cell (SOFC) systems with integrated reformers. For the system considered, onboard reforming ...

Abstract: The theoretical problem addressed in the present work involves the effect of integral feedback on a class of uncertain nonlinear systems. The intriguing aspects of the problem arise as a result of transient constraints ...

Abstract: In the analysis of most engineering dynamical systems, relativistic considerations are unnecessary, allowing an absolute time and simultaneity of events to be assumed. In this article, it is first established that this ...

Abstract: The requirement of satisfying an integral constraint imposed on a linear system's transient step-response is considered in this paper. The problem is first analyzed to determine the specific structure of a system's transfer ...

Abstract: This paper presents a control-oriented model for describing the steady-state and dynamic behavior of a single-winged samara seed-pod in autorotative descent. A negligible lateral center of mass motion and constant, prescribed ...

Abstract: The key control problems associated with variable speed wind turbines are maximization of extracted energy when operating below the rated wind speed, and power and speed regulation when operating above the rated wind speed. ...

Abstract: Loadfollowing in solid oxide fuel cells (SOFCs), hybridized with an ultracapacitor for energy storage, refers to an operating mode where the fuel cell's generated power follows the variable power demand, delivering the ...
