Aspects of Optimization-Based CADCS.
With the recent dramatic increase in available computing power, numerical optimization has become an attractive tool for the design of complex engineering systems. Yet, generalized use of numerical optimization techniques ...
On the Stability of Polynomials with Uncoupled Perturbations in the Coefficients of Even and Odd Powers.
In this note, we present some results concerning the stability (in Hurwitz' sense) of a family of polynomials with even and odd coefficients subject to uncoupled perturbations. It is shown that the stability of an appropriate ...
A New Formula for the Structured Singular Value.
included In TR 85-2
On Feasibility, Descent and Superlinear Convergence in Inequality Constrained Optimization.
Extension of quasi-Newton techniques from unconstrained to constrained optimization via Sequential Quadratic Programming (SQP) presents several difficulties. Among these are the possible inconsistency, away from the solution, ...
On Robust Stability of Linear State Space Models.
The structured singular value (MU), introduced by Doyle  allows to analyze robust stability and performance of linear systems affected by parametric as well as dynamic uncertainty. While exact computation of MU can be ...
User's Guite for FSQP Version 1.0: A Fortran Software for Solving Optimization Problems with General Inequality Constraints and Linear Equality Constraints, Generating Feasible Iterates.
FSQP is a set of Fortran subroutines for the minimization of a smooth objective function subject to nonlinear smooth inequality constraints, linear inequality and linear equality constraints, and simple bounds on the ...
Structured Singular Value and Geometry of the m-Form Numerical Range.
Although the question of the numerical evaluation of Doyle's structured singular value has been repeatedly addressed, it is not yet entirely resolved in the case of block structures of size larger than 3. It has been shown ...
Characterization and Efficient Computation of the Structures Singular Value.
The concept of structured singular value was recently Introduced by Doyle (Proc. IEEE, vol. 129, pp. 242-250, 1982) as a tool for the analysis and synthesis of feedback systems with structured uncertainties. It is a key ...
On Robust Eigenvalue Location.
The concepts of guardian and semiguardian maps were recently introduced as tools for assessing robust generalized stability of parametrized families of matrices or polynomials. Necessary and sufficient conditions were ...
