Сажетак

Sensitivity analysis is the study of changes in system response with respect to design parameters. It is being used in a variety of engineering disciplines ranging from automatic control theory to the analysis of large-scale physiological systems. Some of areas where sensitivity analysis has been applied include: development of insensitive control systems, use in gradient based mathematical programming methods and approximation of system response to change in a system parameter, assessment of design changes on system performance. Eigensensitivity analysis represents a collection of mathematical methods for analyzing structures which is, within dynamical modification, related to sensitivity of eigenvalues and eigenvectors. Therefore, the application of sensitivity analysis is limited to construction of segments for which necessary mathematical relations can be determined. If this is not possible, sensitivity analysis is only
artially applicable.Eigenvalue sensitivity analysis is useful when resonant frequencies need to be restricted. Different methods for analyzing structural eigensensitivity are considered. An example is given to illustrate an optimization problem for a system with repeated frequencies.
