Bifurcations, Chaos and Crises in Power System Voltage Collapse
(1992)
Bifurcations occurring in power system models exhibiting voltage collapse have been the subject of several recent studies. Although such models have been shown to admit a variety of bifurcation phenomena, the view that ...
Nonlinear Dynamics of Axial Flow Compressors: A Parametric Study
(1991)
This paper presents the analysis of the dynamics of a representative axial flow compressor model, emphasizing the influence of two important control parameters. These are a nondimensional parameter B (previously introduced ...
Closed-Loop Monitoring Systems for Detecting Incipient Instability
(1998)
Monitoring systems are proposed for the detection of incipientinstability in uncertain nonlinear systems. The work employsgeneric features associated with the response to noise inputsof systems bordering on instability. ...
Sampled-Data Modeling and Analysis of PWM DC-DC Converters Under Hysteretic Control
(1998)
The PWM DC-DC converter in continuous conduction mode underhysteretic control is modeledand analyzed using the sampled-data approach.This workcomplements other recent work of the authors onsampled-datamodeling and analysis ...
Sampled-Data Modeling and Analysis of PWM DC-DC Converters Part II. The Power Stage
(1998)
The power stage of the PWM DC-DC converter is modeledand analyzed using the sampled-data approach. This workcomplements the companion paper TR 98-54 cite{jbrief} which develops sampled-datamodels and analysis for the ...
Sampled-Data Modeling, Analysis and Control of Load-Resonant DC-DC Converters in Variable Frequency Operation
(1998)
Sampled-data modeling, analysis and control of load-resonant DC-DCconverters in variable frequency operation are considered. A generalblock diagram model is given and then used to obtain a nonlinearsampled-data model ...
Analysis and Control of Period Doubling Bifurcation in Buck Converters Using Harmonic Balance
(1998)
Period doubling bifurcation in buck convertersis studied by using the harmonic balance method.A simple dynamic model of a buck converter in continuous conduction modeunder voltage mode or current mode controlis derived.This ...
Dynamic Bifurcations in a Power System Model Exhibiting Voltage Collapse
(1992)
Dynamic bifurcations, including Hopf and period-doubling bifurcations, are found to occur in a power system dynamic model recently employed in voltage collapse studies. The occurrence of dynamic bifurcations is ascertained ...
On Participation Factors for Linear Systems
(1999)
Participation factors are nondimensional scalars that measure the interaction betweenthe modes and the state variables of a linear system. Since their introduction byVerghese, P'erez-Arriaga and Schweppe, participationfactors ...
Bifurcation Control of chaotic Dynamical Systems
(1992)
A nonlinear system which exhibits bifurcations, transient chaos, and fully developed chaos is considered, with the goal of illustrating the role of two ideas in the control of chaotic dynamical systems. The first of these ...
