The proposed scheme also incorporates a Σ - Δ modulator. The obtained control scheme is developed in two parts: a proportional-integral-type family of algorithms devoted to regulating the uncertain system by using measurements of the output voltage and a Σ - Δ modulator dedicated to transforming the control action into a {0,1} discrete-valued signal. This modulator is a kind of a sliding controller, which can be seen as a subsystem with an on-off output. This combination, the PI-type family of controllers and the Σ - Δ modulator, assures the global stability of the closed-loop system, even if parametric uncertainties are presented. The convergence analysis was carried out using Lyapunov's method. The theoretical results are confirmed using real-time experimental tests, which demonstrate the anti-windup scheme and the Σ - Δ modulator efficiency. The experiments consider the saturation of the control input and disturbances, having obtained convincing results.Instituto Politécnico Nacional 20200671Instituto Politécnico Nacional 20201203Instituto Politécnico Nacional 20201623Ministerio de Ciencia, Innovación y Universidades (España) PGC2018-096265-B-I00Consejo Nacional de Ciencia y Tecnología (México) A1-S-24762Institute of Electrical and Electronics Engineers Inc.Ingeniería de Sistemas y Automática2021info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://hdl.handle.net/11441/105818https://doi.org/10.1109/ACCESS.2021.3054600reponame:idUS.
