Professors Carolina Albea and Alexandre Seuret, attached to the Department of Systems Engineering and Automation of the Higher Technical School of Engineering of the University of Seville, have obtained the International Award for Best Article of the Journal “Nonlinear Analysis: Hybrid Systems” of Elsevier with an impact factor of 5,477, for the work entitled “Time-triggered and event-triggered control of switched affine
systems via a hybrid dynamical approach”. 

International Award for Best Article in the journal Nonlinear Analysis: Hybrid Systems, published by Elsevier

This article presents theoretical results that can be used for the efficient use of power converters found in most electronic devices, such as mobile phones, chargers, computers, vehicles, etc. A quantitative improvement in the efficiency of these devices leads to a positive impact on reducing energy consumption.

This article presents two methodologies for designing control signals for affine switched systems: one sampled at periodic time intervals and the other sampled by events, using a hybrid dynamic systems approach. The distinguishing feature of event sampling is that such sampling is only permitted when a specific event is detected. 
The novel aspects of this article are: the hybrid dynamic representation of this class of systems; the design of minimum projection control laws with free matrices, which relax the usual minimum projection control structure, generally based on the Lyapunov matrix; and, finally, the formulation of a stabilization result that guarantees that an attractor, defined as a neighborhood of the desired operating point, is uniformly, globally, and asymptotically stable with both control laws.

On July 14th, the presentation of this international award will take place in Yokohama, Japan, at the closing ceremony of the “IFAC World Conference”, where the International Federation of Automatic Control (IFAC) will present its most important triennial awards, such as this one.
