Fast frequency response computation for Rayleigh damping

, 2006
We present a model reduction Lanczos method for the computation of frequency response functions of Rayleigh damping problems. The connection with modal extraction and modal superposition is made. The usual model reduction methods require complex arithmetic. With the proposed method, complex arithmetic is only used for the reduced problem.

GraFIT: A toolbox for fast and accurate frequency response identification in gravitational wave detectors

Review of Scientific Instruments
Frequency Response Function (FRF) measurements are widely used in gravitational wave detectors, e.g., for the design of controllers, calibrating signals, and diagnosing problems with system dynamics. The aim of this paper is to present GraFIT: a toolbox that enables fast, inexpensive, and accurate identification of FRF measurements for gravitational ...

Adaptive Dual Droop for Active Power‐Frequency Control in Power System With Photovoltaic System

IET Renewable Power Generation
As the penetration of photovoltaic systems (PVs) increases, the ability to control network frequency becomes limited. Traditional PV control typically relies on maximum power point tracking (MPPT); however, in MPPT mode, PVs cannot contribute to ...
