In our previous work 1] we have studied natural mechanical systems on Riemannian manifolds with a strong constraining potential. These systems establish fast nonlinear oscillations around some equilibrium manifold. Important in applications, the problem of elimination of the fast degrees of freedom, or homogeniza-tion in time, leads to determine the singular limit of innnite strength of the con...

This article discusses the coupled microvibration analysis of a cantilever configured Reaction Wheel Assembly with soft-suspension system. A RWA–seismic mass coupled microvibration measurement system is presented and its model validated against test results. The importance of the RWA driving point accelerances in coupled microvibration designed to measure the driving point accelerances in both ...

Abstract: Wind turbine plants are complex dynamic and uncertain processes driven by stochastic inputs disturbances, as well different loads represented gyroscopic, centrifugal, gravitational forces. Moreover, their aerodynamic models nonlinear, both modelling control become challenging problems. On one hand, high–fidelity simulators should contain parameters variables in order to accurately des...
