Neste artigo, investigamos um projeto livre de modelo de mecanismo descentralizado acionado por eventos para sistemas de controle em rede (NCSs). A abordagem visa ajustar simultaneamente os parâmetros ótimos para o controlador e a condição disparada pelo evento, de modo que uma função de custo prescrita possa ser minimizada. Para atingir esse objetivo, empregamos o Otimização Bayesiana (BO), que é conhecido por ser uma estrutura de ajuste automático para encontrar a solução ótima para o problema de otimização de caixa preta. Graças à sua eficiente estratégia de busca pelo ótimo global, o BO nos permite projetar o mecanismo disparado por eventos com um número relativamente pequeno de avaliações experimentais. Isto é particularmente adequado para NCS onde os recursos de rede, como a vida útil limitada dos dispositivos alimentados por bateria, são limitados. Alguns exemplos de simulação ilustram a eficácia da abordagem.

Abstract: In this paper, we investigate a model-free design of decentralized event-triggered mechanism for networked control systems (NCSs). The approach aims at simultaneously tuning the optimal parameters for the controller and the event-triggered condition, such that a prescribed cost function can be minimized. To achieve this goal, we employ the Bayesian optimization (BO), which is known to be an automatic tuning framework for finding the optimal solution to the black-box optimization problem. Thanks to its efficient search strategy for the global optimum, the BO allows us to design the event-triggered mechanism with relatively a small number of experimental evaluations. This is particularly suited for NCSs where network resources such as the limited life-time of battery powered devices are limited. Some simulation examples illustrate the effectiveness of the approach.
