Frequency Response Functions for Nonlinear Convergent Systems

IEEE Transactions on Automatic Control, 2007
Convergent systems constitute a practically important class of nonlinear systems that extends the class of asymptotically stable linear time-invariant systems. In this note, we extend frequency response functions defined for linear systems to nonlinear convergent systems.

Interconnected system frequency response

Proceedings of 28th Southeastern Symposium on System Theory, 2002
Frequency management is a primary goal in the control of an electric power system. Traditionally, this has been accomplished via tie-line bias control within a well defined control area. However, the control area's frequency bias characteristic, which is an important component in the tie-line bias control equation, is a difficult term to quantify. This

The Frequency Response of Automatic Control Systems

Transactions of the American Institute of Electrical Engineers, 1946
This paper illustrates the advantages of the frequency response approach to the analysis of automatic control systems, as contrasted to the analytic solution of transient responses. At the same time the equivalence of information available from the two approaches is demonstrated.

The Frequency Response of Optical Systems

Proceedings of the Physical Society. Section B, 1956
In optical systems the pencils forming images of extra-axial object points are generally oblique to both the object and image planes. The diffraction image of a point source observed in an oblique image plane differs significantly from that obtained in a plane normal to the image-forming pencil.

Frequency Response of Apodized Systems

Optica Acta: International Journal of Optics, 1974
The frequency responses of eight apodized systems with circular aperture have been investigated. The apodization has been done by dividing the aperture into two and three rings of different areas either by using a π -phase distribution or by amplitude transmittance variations in the different rings.

Notes on linear systems and frequency responses

International Journal of Circuit Theory and Applications, 2005
Summary: We show that not all continuous multidimensional linear shift-invariant systems are characterized by their frequency responses (even when they exist), but that the members of a certain important large family of multidimensional linear systems are completely characterized by their suitably defined frequency responses.

Frequency Response Of Linear Systems With Parameter Uncertainties

Journal of Sound and Vibration, 1993
Abstract The primary objective of the present study is to develop a new analytical method for estimating the frequency response characteristics of a linear time-variant, discrete vibratory system when the mass, stiffness and damping parameters are uncertain.
