TL;DR: In this article, two types of finite impulse response (FIR) filters are proposed to reconstruct dynamic displacement induced by structural vibration from measured acceleration, which is derived by taking the variation of a minimization problem, which defines an inverse problem on displacement.

TL;DR: In this paper, an efficient pole-placement method is developed with straightforward formulation and a reduced computation requirement for an unstable nine-machine system, which not only ensures the exact pole-position of the unstable mechanical modes, but also improves the dampings of the poorly damped mechanical modes.
Abstract: Power system stabilizers (PSS) are designed for an unstable nine-machine system. Participation factors are used to select the sites and number of stabilizers. An efficient pole-placement method is developed with straightforward formulation and a reduced computation requirement. The design not only ensures the exact pole-placement of the unstable mechanical modes, but also improves the dampings of the poorly damped mechanical modes, resulting in a well-coordinated damping for the entire system. >

TL;DR: In this article, it was shown that scalar diffraction phenomena (conical diffraction from gratings) are shift-invariant with respect to incident angle only in direction cosine space, and surface roughness can be considered to be composed of a superposition of sinusoidal phase gratings.
Abstract: Empirical experimental scattering data from conventional optical surfaces is shown to exhibit shift-invariant behavior with respect to incident angle when plotted in direction cosine space. This implies the existence of a surface transfer function that completely characterizes the scattering properties of the surface, and permits the application of linear systems theory and Fourier techniques in modeling the scattering effects of optical surfaces. A theoretical basis for this behavior is illustrated by showing that scalar diffraction phenomena (conical diffraction from gratings) is shift-invariant with respect to incident angle only in direction cosine space, and surface roughness can be considered to be composed of a superposition of sinusoidal phase gratings. The fact that many optical surfaces of interest deviate from this shift-invariant behavior does not invalidate the usefulness of the linear systems formalism. The ideal behavior of a shift-invariant scattering process can still be used for making engineering calculations and retained as the reference from which scattering from real surfaces is compared. This is completely analogous to the universally accepted transfer function characterization of imaging systems in spite of the fact that few real imaging systems are isoplanatic (no field-dependent aberrations).
