On Continuity/Discontinuity in Robustness Indicators
(1991)
Continuity/discontinuity of robustness indicators is reviewed. For the case of real or mixed uncertainty, a regularization of the frequency dependent robustness margin is proposed and its properties are discussed. Implication ...
An SQP Algorithm for Finely Discretized Continuous Minimax Problems and Other Minimax Problems with Many Objective Functions
(1993)
A common strategy for achieving global convergence in the solution of semi-infinite programming (SIP) problems, and in particular of continuous minimax problems, is to (approximately) solve a sequence of discretized problems, ...
User's Guide for ADIFFSQP Version 0.91
(1997)
ADIFFSQP is a utility program that allows to user of the FFSQP[1] constrained nonlinear optimization routines to invoke the computational differentiation (or automatic differentiation:AD) preprocessor ADIFOR2.0 [2] conveniently
Absolute Stability Theory, Theory, and State-Space Verification of Frequency-Domain Conditions: Connections and Implications for Computation
(1997)
The main contribution of the paper is to show the equivalence between the following two approaches for obtaining sufficient conditions for the robust stability of systems with structured uncertainties: (i) apply the classical ...
An SQP Algorithm for Finely Discretized SIP Problems and Other Problems with Many Constraints
(1992)
A Common strategy for achieving global convergence in the solution of semi-infinite programming (SIP) problems is to (approximately) solve a sequence of discretized problems, with a progressively finer discretization mesh. ...
Fast Feasible Direction Methods, with Engineering Applications
(1991)
Optimization problems arising in engineering applications often present distinctive features that are not exploited, or not accounted for, in standard numerical optimization algorithms and software codes. First, in many ...
A New Class of Six-Bar Mechanisms with Symmetrical Coupler Curves
(1996)
A new class of six-bar mechanisms with symmetrical coupler-point curves is presented. This class of mechanisms is made up of a four-bar linkage with an additional dyad to form an embedded regular or skew pantograph. Because ...
Multiobjective Optimization of a Leg Mechanism with Various Spring Configurations for Force Reduction
(1996)
In this paper, the design of a two degree-of-freedom leg mechanism is accomplished by a two-stage optimization process. In the first stage, leg dimensions are optimized with respect to three design objectives: minimize (i) ...
Robustness under Bounded Uncertainty with Phase Information
(1996)
We consider uncertain linear systems where the uncertainties, in addition to being bounded, also satisfy constraints on their phase. In this context, we define the ﲰhase-sensitive structured singular value (PS-SSV) of a ...
