Array pattern synthesis using semidefinite programming and a bisection method

open access: yesETRI Journal, 2019
In this paper, we propose an array pattern synthesis scheme using semidefinite programming (SDP) under array excitation power constraints. When an array pattern synthesis problem is formulated as an SDP problem, it is known that an additional rank‐one ...

Control Systems Design With Enlarged Stability Domains for Nonlinear Constrained Systems via Sum‐of‐Squares Optimization

open access: yesInternational Journal of Robust and Nonlinear Control, Volume 36, Issue 14, Page 6856-6876, 25 September 2026.
ABSTRACT Designing safe control laws for nonlinear systems is challenging, especially when ensuring stability under actuator saturation and state constraints. A key aspect is embedding controllers with a Region of Attraction (ROA), which defines initial conditions guaranteeing convergence to a stable equilibrium point (EP).

Exploiting Sparsity in SDP Relaxation for Harmonic Balance Method

open access: yesIEEE Access, 2020
In general, harmonic balance problems are extremely nonconvex and difficult to solve. A convex relaxation in the form of semidefinite programming has attracted a lot of attention recently, as it finds a global solution with high accuracy without the need

Coordinated scheduling for transmission-distribution-microgrids via chordal-based semidefinite programming

open access: yesInternational Journal of Electrical Power & Energy Systems
With the accelerating integration of distributed energy resources (DERs) into grids, enhanced bidirectional interactions between distribution and transmission systems have significantly complicated grid coordination.

Quantum Alternating Direction Method of Multipliers for Semidefinite Programming [PDF]

open access: yesQuantum
Semidefinite programming (SDP) is a fundamental convex optimization problem with wide-ranging applications. However, solving large-scale instances remains computationally challenging due to the high cost of solving linear systems and performing ...

Generalized Gauss Inequalities via Semidefinite Programming

open access: yes
A sharp upper bound on the probability of a random vector falling outside a polytope, based solely on the first and second moments of its distribution, can be computed efficiently using semidefinite programming.

Bounds for codes by semidefinite programming [PDF]

open access: yesProceedings of the Steklov Institute of Mathematics, 2008
Delsarte's method and its extensions allow to consider the upper bound problem for codes in 2-point-homogeneous spaces as a linear programming problem with perhaps infinitely many variables, which are the distance distribution. We show that using as variables power sums of distances this problem can be considered as a finite semidefinite programming ...

Semidefinite Programming for Approximate Maximum Likelihood Sinusoidal Parameter Estimation

open access: yesEURASIP Journal on Advances in Signal Processing, 2009
We study the convex optimization approach for parameter estimation of several sinusoidal models, namely, single complex/real tone, multiple complex sinusoids, and single two-dimensional complex tone, in the presence of additive Gaussian noise.

A Reduced Semidefinite Programming Formulation for HA Assignment Problems in Sport Scheduling

open access: yesTrends in Computational and Applied Mathematics, 2018
Home-Away Assignment problems are naturally cast as quadraticpro gramming models in binary variables. In this work we compare alternative formulations for this kind of problems.
