Sánchez-Torres, "Second Order Sliding Mode Control of a STATCOM with Saturated Inputs," 2018 15th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), Mexico City, 2018, pp. 1-6. doi: 10.1109/ICEEE.2018.8533951978-1-5386-7033-0http://hdl.handle.net/11117/5780This paper presents a robust controller for a STATCOM device with saturated inputs. As the primary assumption, the proposed design considers the presence of unknown but bounded external perturbations and parametric variations. This proposal has a cascade structure, where a saturated super twisting control algorithm closes the currents control loop, and a high-gain proportional-integral (PI) algorithm ensures the voltage regulation. Thus, the exposed scheme provides an adequate performance of the STATCOM, considering the saturation of the inputs with the anti-windup feature. Posteriorly, a proper stability analysis presents the conditions for the appropriate operation of the closed-loop system in saturation and non-saturation regimes. Numerical simulations are also included to show the performance of the proposed controller.engNonlinear systemsLyapunov stabilityRobust controlSliding mode controlinfo:eu-repo/semantics/conferencePaper
