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.2021http://zaguan.unizar.es/record/10669510.1016/j.ifacol.2020.12.1738http://zaguan.unizar.es/record/106695oai:zaguan.unizar.es:106695info:eu-repo/grantAgreement/ES/DGA-FEDER/2014-2020info:eu-repo/grantAgreement/ES/DGA/T45-17Rinfo:eu-repo/grantAgreement/ES/MCIU-AEI-FEDER/PGC2018-098719-B-I00info:eu-repo/grantAgreement/ES/MEC/FPU14-04171info:eu-repo/grantAgreement/ES/MICINN-AEI-FEDER/RTC-2017-5965-6IFAC PAPERSONLINE 53, 2 (2021), 6256-6261by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
