Soft-landing control strategies aim at minimizing the impact velocities of these devices to improve their performance. This paper presents a sliding-mode controller for soft landing of single-coil reluctance actuators. It is a switching model-free controller, which results in a very simple implementation. A generalized dynamical hybrid model of an actuator is utilized for deriving the robustness condition, based on the Lyapunov theory. Then, the condition is evaluated for a dynamical model, based on a commercial device, and several reference trajectories. Finally, the controller performance is validated through simulations. The effect of the sampling rate on the resulting impact velocities is also analyzed. info:eu-repo/grantAgreement/ES/DGA-FEDER/2014-2020 info:eu-repo/grantAgreement/ES/DGA/T45-17R info:eu-repo/grantAgreement/ES/MCIU-AEI-FEDER/PGC2018-098719-B-I00 info:eu-repo/grantAgreement/ES/MEC/FPU14-04171 info:eu-repo/grantAgreement/ES/MICINN-AEI-FEDER/RTC-2017-5965-6 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 0.324 2021 Control and Systems Engineering 2021 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ramirez-Laboreo, Edgar Universidad de Zaragoza (orcid)0000-0002-8977-5296 Sagues, Carlos Universidad de Zaragoza (orcid)0000-0002-3032-954X 5007 520 Universidad de Zaragoza Dpto.
