Minimização de Perturbações em Bombas Elétricas Submersas Utilizando Controladores Robustos e Ferramentas de Aprendizado de Máquina

Abstract

This paper proposes a control strategy consisting of a robust controller and an Echo State Network (ESN) based control law for stabilizing a class of uncertain nonlinear discrete-time systems subject to persistent disturbances. Firstly, the robust controller is designed to ensure that the closed-loop system is Input-to-State Stable (ISS) with a guaranteed stability region regardless of the ESN control action and exogenous disturbances. Then, the ESN based controller is trained in order to mitigate the effects of disturbances on the system output. The proposed approach is applied to an Electric Submersible Pump (ESP) to mitigate the effects of exogenous disturbances.
