Expected angle stability margin

SMC'98 Conference Proceedings. 1998 IEEE International Conference on Systems, Man, and Cybernetics (Cat. No.98CH36218), 2002
This paper develops a novel concept and computational framework of the expected angle stability margin (EASM) in electrical power systems. This new integrated index provides a common transient (angle) stability characteristic over a set of possible system configurations and contingencies, disturbances and faults, and load demand levels.

STABILITY MARGIN AND SPHERICAL UNCERTAINTY

Cybernetics and Systems, 2006
The article addresses the stability margin of multivariable dynamic systems as a comprehensive study of the influence of the uncertainties on the stability margin. Spherical uncertainties of a given norm are considered, minimal in Frobenius norm sense, producing a maximum influence on the stability margin of the system.

DIRECT CALCULATION OF STABILITY MARGINS

IFAC Proceedings Volumes, 1994
Abstract A novel method is presented, which has been developed to compute stability margins in the parameter space and other related characteristics of linear control loops in a direct and efficient manner using methods of linear algebra. The algebraic representation of stability margins in terms of a pencil of resultant matrices opens the ...

Stability Margins and Digital Implementation of Controllers

Proceedings of the 1998 American Control Conference. ACC (IEEE Cat. No.98CH36207), 1998
This paper investigates the robustness and related behaviour of control systems containing a digital implementation of a designed continuous time controller, mainly through examples. We determine the coefficient stability margin of the digital controller as the sampling time is varied.

The Intertemporal Stability of the Concentration-Margins Relationship

The Journal of Industrial Economics, 1986
Using a longitudinal data base, we find that there has been a substantial narrowing of the spread between the price-cost margins of concentrated and unconcentrated industries. Including measures of macroeconomic fluctuations into standard price-cost margin regressions, we find significant differences in cyclical behavior across market structure.

Stability and stability margin for a two-dimensional system

IEEE Transactions on Signal Processing, 2006
In this paper, a necessary and sufficient condition is derived for the stability of the Fornasini-Marchesini (FM) first model proposed for two-dimensional (2-D) dynamic system descriptions. A connection has been established between the stability of this model and the structured singular value (SSV) of a constant matrix, which is now widely known in ...

PEBB System Stability Margin Monitoring

Journal of Vibration and Control, 2002
PEBB (power electronics building block) systems are typical nonlinear systems. Under the conventional but still popular linear control design, the system stability margin varies from one operating point to another. This paper introduces a novel approach to monitoring the DC bus stability margin of a PEBB system online.

Stability margins of linear prediction polynomials

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
This paper performs a detailed analysis of the zero location of linear predictor polynomials and in particular determines a precise stability margin for some classical predictors such as the autocorrelation and the postwindowed cases. It is shown that an adequate mathematical tool in this context is the concept of numerical range or field of values of ...

Stability margin of a closed interval system

International Journal of Systems Science, 1998
The stability margin of a closed system under the interval perturbation mode is studied using the concpet of H-equivalence and the means of geometric analysis in the complex plane. The problem is converted to a one-dimensional mathematical program. The solution of the program gives the stability margin which can be used to check the robust stability of
