Response of a Loaded Nonlinear String to Random Excitation
Journal of Applied Mechanics, 1962The response to white noise excitation of a light elastic string loaded at equal intervals by a number of equal masses is examined using the theory of the Markov random process and the associated Fokker-Planck equation. Taking nonlinear effects due to variation in string tension into account, an exact solution of the Fokker-Planck equation is obtained ...

Lateral Load Analysis of Nonlinear Piles
Journal of Geotechnical Engineering, 1988Analysis of the response of pile foundations to lateral loads requires accurate characterization of the behavior of the pile and the soil surrounding the pile. The common assumption of pile linearity in bending may not be valid in many cases. A model for representing nonlinear pile bending behavior in the analysis of laterally loaded piles is ...

Nonlinear vibration of a loaded string in energy harvesting
Smart Materials and StructuresAbstract Designing wideband energy harvesters using beam structures typically involves complexities, particularly in low-frequency and low-energy environments where the limitations of beam structures become more evident. To address these challenges, this study proposed a strategy for energy harvesting using a loaded-string system and ...

A Nonlinear Load-Frequency Control Design
IEEE Transactions on Power Apparatus and Systems, 1978A load frequency control for a two-area interconnected system is designed taking into account the nonlinearity and stochasticy of the load and using an optimal linear strategy aided by stability analysis. An observer is proposed for its implementation. A coordinating control for the two area system based on acceleration feedback is suggested.

Power factor improvement for nonlinear loads
[Proceedings] IEEE 1991 Annual Textile, Fiber and Film Industry Technical Conference, 2002Power factor correction through the application of capacitors to electrical systems is addressed, with particular reference to avoiding problems in systems where large nonlinear loads producing harmonic distortion are present. Power factor is reviewed, and a method for designing a power factor correction is presented. The approach has been successfully

On the equilibria of power systems with nonlinear loads
IEEE Transactions on Circuits and Systems, 1989A discussion is presented of various structure-preserving models for power systems along with their differential-algebraic and local-normal-form representations. The different models emanate from a variety of the generator and load damping properties. The equilibria of interest reflect the bus power imbalance after a fault and depend on the nature of ...
