This paper presents a new control approach that aims at achieving soft landing in these devices, i.e., a movement without neither impacts nor bouncing. The hybrid nonlinear dynamics of the system is firstly described taking into account the limited range of motion that characterizes this class of devices. Then, the nonlinear expression of the control law is derived and a method to design a soft-landing reference trajectory is proposed. It is shown that, when certain conditions are met, the design methodology presented in the paper results in a controller that achieves perfect tracking of the reference trajectory and, hence, soft landing is accomplished. The theoretical analysis is validated by simulation using a dynamical model of a specific switching device. info:eu-repo/grantAgreement/ES/DGA-FEDER/2014-2020 info:eu-repo/grantAgreement/ES/DGA/T45-20R 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/MICIU/RTC-2017-5965-6 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 5.2 2023 MECHANICS 14 / 170 = 0.082 2023 Q1 T1 ENGINEERING, MECHANICAL 22 / 183 = 0.12 2023 Q1 T1 1.23 2023 Aerospace Engineering 2023 Q1 Applied Mathematics 2023 Q1 Ocean Engineering 2023 Q1 Control and Systems Engineering 2023 Q1 Mechanical Engineering 2023 Q1 Electrical and Electronic Engineering 2023 Q1 9.0 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Moya-Lasheras, Eduardo Universidad de Zaragoza (orcid)0000-0001-6244-3366 Sagues, Carlos Universidad de Zaragoza (orcid)0000-0002-3032-954X 5007 520 Universidad de Zaragoza Dpto.
