Sum-of-Squares Relaxations for Information Theory and Variational Inference
Foundations of Computational Mathematics, 2022We consider extensions of the Shannon relative entropy, referred to as f-divergences. Three classical related computational problems are typically associated with these divergences: (a) estimation from moments, (b) computing normalizing integrals, and (c)

Extended bounded real lemma based sum of squares for static output feedback H∞ heading control
International Journal of Robust and Nonlinear Control, 2022Aim at the fore and aft asymmetry of unmanned surface vehicle (USV) and the loss of linear velocity, a static output feedback (SOF) H∞$$ {H}_{\infty } $$ control method is proposed by the sum of squares (SOS) based on two types of extended bounded real ...

Hamiltonian‐driven adaptive dynamic programming for mixed H2/H∞ performance using sum‐of‐squares
International Journal of Robust and Nonlinear Control, 2021In this article, the mixed H2/H∞ performance optimization is first formulated as a nonzero‐sum game, of which the sufficient condition guaranteeing the existence of the Nash equilibrium is derived using the Hamilton–Jacobi (HJ) theory.

Sum‐of‐squares‐based policy iteration for suboptimal control of polynomial time‐varying systems
Asian journal of control, 2021This paper investigates the suboptimal control design for polynomial time‐varying systems. It is known that the solution to this problem relies on the solution of the Hamilton–Jacobi–Bellman (HJB) equation, which is a nonlinear partial differential ...

A study over the general formula of regression sum of squares in multiple linear regression
Numerical Methods for Partial Differential Equations, 2020In this study, in addition to the formula of regression sum of squares (SSR) in linear regression, a general formula of SSR in multiple linear regression is given. The derivations of the formula presented are given step by step.

In this paper, we propose a novel controller design approach for unknown nonlinear systems using the Koopman operator. In particular, we use the recently proposed stability- and feedback-oriented extended dynamic mode decomposition (SafEDMD) architecture
