Finite-time ESO-based two-stage robust model-free predictive control for flexible interconnecting device

This article is concerned with an innovative approach to improve control performance for flexible interconnecting devices. Specifically, a finite-time extended state observer-based two-stage robust model-free predictive control is proposed to enhance the robust performance and to attenuate the unnecessary switching loss. The two key features of this suggested control protocol that, first, a two-stage robust model-free predictive control is developed to reduce the switching frequency while ensuring system performance, and, second, a finite-time extended state observer is leveraged to attenuate the parametric uncertainties. Finally, we illustrate our control methodology on a numerical example, and performance evaluations validate its effectiveness, thus promising more efficient and robust control techniques for practical applications.
