Stability in Nonlinear Programming

Operations Research, 1970
This paper establishes necessary and sufficient conditions for constraint set stability requiring neither convex constraint functions not convex constraint sets. These conditions then lead to a sufficiency result for the continuity of the optimal objective values as the right-hand side varies. Applications to quasiconvex functions are presented.

Optimization for Nonlinear Stability

Civil-Comp Proceedings, 1988
Abstract This paper is concerned with the optimal design of trusses to withstand nonlinear stability requirements. While basically a geometrically nonlinear problem, nonlinear stability accounts for large rotations and equilibrium in the deformed state in contrast to linear stability which results in a generalized eigenvalue problem and handles small

Rates of Stability in Nonlinear Programming

Operations Research, 1976
We give conditions on a nonlinear programming problem for the set of feasible solutions to have stability on the order of a Lipschitz condition. These results then imply conditions for the optimal value of the objective function to satisfy a Lipschitz condition with respect to the right-hand side vector as well as for the set of ϵ-optimal solutions to

Stabilization of Beams with Nonlinear Feedback

SIAM Journal on Control and Optimization, 2002
The author studies a simplified form of the dynamic Euler-Bernoulli beam equation for coupled beams: \(y''+\partial^4y/\partial x=0\), where \(y''\) stands for \(\partial^2y/\partial t^2\), \(t>0\), \(x\in(0,a)\cup (a,1)\), with a coupling point at \(x=a\). It is simply supported at \(x=0\), with shear hinge condition at \(x=1\) in model \(\#1\), it is

Stability of positive nonlinear systems

2017 22nd International Conference on Methods and Models in Automation and Robotics (MMAR), 2017
The stability of time-invariant positive nonlinear systems is addressed. Necessary conditions for the stability of positive time-invariant continuous-time and discrete-time nonlinear systems are established. It is shown that the positive nonlinear systems are asymptotically stable only if the corresponding positive linear systems are asymptotically ...

STABILIZATION OF PLANAR NONLINEAR SYSTEMS

IFAC Proceedings Volumes, 1992
Abstract In this paper, we investigate the C1-stabilizability of affine control nonlinear systems in the plane. The feedback laws are given by means of Center manifold machinery.

Nonlinear stabilization with bounded controller

2015 10th Asian Control Conference (ASCC), 2015
This In this paper, an extension of the Sontag's universal formula is proposed. For benchmark, the proposed method is compared with two other approaches, i.e. a universal Sontag's formula and a direct Lyapunov with comparing square. To observe the efficacy of the proposed method, a numerical nonlinear system with cubic damping is stabilized.

Nonlinear Stability of Hybrid Control

The International Journal of Robotics Research, 1998
A theoretical and experimental investigation on the stability proper ties of the hybrid control scheme was performed using Lyapunov's theory for both the original scheme, which uses the Jacobian in verse for mapping Cartesian errors to joint errors, and a scheme using the Jacobian pseudoinverse.
