On frequency response analysis of GPIO
2015 American Control Conference (ACC), 2015The Generalized Proportional Integral Observer (GPIO), which is a generalized high order Extended State Observer (ESO), has drawn much attention from both the industry and academia recently. This paper explores the characteristics of GPIO for the linear, time-invariant (LTI) plants using the frequency response method.

Over the last few decades it has been recognized that Frequency Response Analysis (FRA) is a reliable method for detecting dimensional changes in the transformer windings. Out of the two methods of FRA, swept frequency response analysis (SFRA) has gained popularity over the impulse frequency response analysis (IFRA) with the passage of time, although ...

Frequency response analysis of the diaphragm in vivo
Journal of Applied Physiology, 1976Frequency response analysis was used to determine the dynamic response characteristics of cat diaphragm under isovolumetric conditions at functional residual capacity (FRC) and at lung volumes above and below FRC. In apneic cats, sinusoidally modulated pulse rate patterns were applied to both phrenic nerves.

Analysis of the frequency following response in the cat
Hearing Research, 1984The generators of the frequency following response (FFR) were characterized for three frequency ranges by studying changes in FFR response after lesioning the nuclei within the central brainstem auditory pathway. Responses to low frequency (200-500 Hz) stimulation demonstrated changes in the complexity of the FFR waveform in both time and frequency ...

Time–Frequency Analysis of the Impulse Response
IEEE Transactions on Signal Processing, 2019The impulse response is a key function for the analysis and design of systems, therefore understanding its properties is a fundamental problem. To investigate the nonstationary structure of the impulse response, we derive its time–frequency representation both in the Wigner and smoothed Wigner distribution domains.

Transformers can be treated as a time-invariant system which can be characterized by its response to the Dirac's delta function. This impulse response is completely unique and should remain so over the system life. Therefore, it can be used as a kind of indicator to check if the internal compartments, elements or parameters have physically changed ...

An analysis of frequency response on OLED for lighting applications
2017 IEEE Industry Applications Society Annual Meeting, 2017Organic light-emitting diodes (OLEDs) are a new technology with great potential for lighting applications. They have a large area providing a comfortable light and a good thermal dissipation. Once the OLEDs applications in lighting are recently, is necessary to create an electrical equivalent model for their analysis, because this knowledge is ...

Sensitivity Analysis of the Frequency Response of a Piecewise Linear System in a Frequency Island
Journal of Vibration and Control, 2004In this paper, we analyze the frequency response of a piecewise linear suspension system. Dynamical characteristics of the suspension will suddenly change when its relative displacement exceeds a clearance. Piecewise linear characteristics occur, for example, wherever we use stoppers to prevent the system from excessive relative displacement.

Frequency response analysis of slot coating
AIChE Journal, 2010AbstractFrequency responses to the slot die coating process is analyzed using empirical modal analysis to predict the effects of periodic process disturbances such as gap oscillation and variations in vacuum pressure, web velocity, and flow rate. A type of empirical modal analysis known as an experimental modal approach was used, and an oscillator ...
