Fuzzy Frequency Response for Complex Dynamic Systems

2010 IEEE International Symposium on Intelligent Control, 2010
Fuzzy Frequency Response: Definition and Analysis for Complex Dynamic Systems is proposed in this paper. In terms of transfer function, the complex dynamic system is partitioned into several linear sub-models and it is organized into Takagi-Sugeno (TS) fuzzy structure.

Neural control of nonlinear systems by frequency response

IJCNN'99. International Joint Conference on Neural Networks. Proceedings (Cat. No.99CH36339), 2003
The purpose of this paper is to introduce a methodology for analysis and design of nonlinear control systems using neural networks and frequency response information. The approach is grounded in solid control engineering practice and notions, and provides a natural design procedure that establishes strong conceptual links between neural networks and ...

Computation of the 2D system frequency response

[1988] Proceedings. The Twentieth Southeastern Symposium on System Theory, 1989
A technique for the computation of the magnitude and phase of 2D systems is presented. This technique is based on the extension of a 1D algorithm. The algorithm does not require any complex arithmetic, and can easily be implemented a personal computer, on which it requires less storage than the 2D discrete Fourier transform algorithm. >

On the frequency response of scalar discrete-time systems

Automatica, 1999
Gain and phase characteristics of real and complex discrete-time zeros and poles are considered. The frequency response of polynomials in \(z\) is obtained by varying \(z\) around the unit circle. The minimum and the maximum of the gain values are determined for different parameters.

Frequency response of uncertain systems with interval plants

IEEE Transactions on Automatic Control, 1993
Summary: This note provides simplification results concerning frequency domain properties of systems containing an interval plant. The problem is formulated in a general enough manner to encompass most problems involving one interval plant. It is shown that under rather mild assumptions, all the key information can be obtained using just 32 one ...

Sensitivity Analysis of the Frequency Response of a Piecewise Linear System in a Frequency Island

Journal of Vibration and Control, 2004
In 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.

Computation of the frequency response of multilinear affine systems

IEEE Transactions on Automatic Control, 2002
Deals with the problem of computing the frequency response of an uncertain transfer function whose numerator and denominator polynomials are multiples of independent uncertain polynomials of the form P(s, q) = l/sub o/ (q) + l/sub 1/ (q) s + /spl middot//spl middot//spl middot/ + l/sub n/, (q) s/sup n/ whose coefficients depend linearly on q = [q/sub 1/

Steady-state frequency response for periodic systems

Journal of the Franklin Institute, 2001
This paper extends the concept of steady-state frequency response, well known in the theory of linear time-invariant (LTI) systems, to linear time-varying systems with periodic coeAcients, called periodic systems. It is shown that for an internally stable periodic system there exist complete orthogonal systems of real periodic functions ff n g and fc n

Frequency Response Sensitivity Functions for Helicopter Frequency Domain System Identification

Journal of the American Helicopter Society, 1997
This paper addresses some aspects of frequency domain based, state space system identification. A frequency response sensitivity function is developed, and applied to the problem of identifying a coupled rotor-fuselage helicopter model from simulated frequency sweep data.

On the frequency response of semiconductive shields for power systems applications

2012 IEEE International Workshop on Applied Measurements for Power Systems (AMPS) Proceedings, 2012
Semiconductive materials are widely used in power systems components such as cables and connectors. Their role is to shield and control electric fields emitted by primary components thus helping to fulfill, amongst other things, electromagnetic compatibility (EMC) requirements of the kind of the apparatus in which they are used.
