PENNON: Software for Linear and Nonlinear Matrix Inequalities [PDF]
, 2011 The goal of this paper is to present an overview of the software collection for the solution of linear and nonlinear semidefinite optimization problems PENNON. In the first part we present theoretical and practical details of the underlying algorithm and several implementation issues.

Risk‐aware safe reinforcement learning for control of stochastic linear systems
Asian Journal of Control, EarlyView.Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Modeling and parameter estimation for fractional large‐scale interconnected Hammerstein systems
Asian Journal of Control, EarlyView.Abstract This paper addresses the challenge of modeling and identifying large‐scale interconnected systems exhibiting memory effects, hereditary properties, and non‐local interactions. We propose a fractional‐order extension of the Hammerstein architecture that incorporates Grünwald–Letnikov operators to capture complex dynamics through multiple ...

IEEE Access, 2018 In this paper, the stability and stabilization problems are investigated for a class of event-triggered multiple time delays network control systems. Under the conditions of the event-triggered scheme and the system state estimation, the delays in the ...

Asian Journal of Control, EarlyView.Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

British Educational Research Journal, EarlyView.Abstract With growing attention to student agency in academic and policy discourse, international education has become a prominent context for examining how students navigate new cultural, academic, linguistic and social environments. However, much of this discussion attributes student agency to the ‘international’ aspect, while overlooking the ...

ON A GENERALIZATION OF THE MAXIMUM ENTROPY THEOREM OF BURG
Revista de Matemática: Teoría y Aplicaciones, 2017 In this article we introduce some matrix manipulations that allow us to obtain a version of the original Christoffel-Darboux formula, which is of interest in many applications of linear algebra. Using these developments matrix and Jensen’s inequality, we

British Educational Research Journal, EarlyView.Abstract Research evidence is mixed on the consequences of ability grouping policies, but most research has found an overrepresentation of disadvantaged social demographics in low‐ability groups. However, researchers have neglected to explain why ability grouping policies vary between countries.
