The application of soft-landing control strategies to these devices aims at minimizing the impact velocities of their moving components to ultimately improve their lifetime and performance. In this brief, a novel approach for soft-landing trajectory planning, including probability functions, is proposed for optimal control of the actuators. The main contribution of the proposal is that it considers the uncertainty in the contact position, and hence, the obtained trajectories are more robust against system uncertainties. The problem is formulated as an optimal control problem and transformed into a two-point boundary value problem for its numerical resolution. Simulated and experimental tests have been performed using a dynamic model and a commercial short-stroke solenoid valve. The results show a significant improvement in the expected velocities and accelerations at contact with respect to past solutions in which the contact position is assumed to be perfectly known. info:eu-repo/grantAgreement/ES/DGA/T45-17R info:eu-repo/grantAgreement/ES/MEC/FPU14-04171 info:eu-repo/grantAgreement/ES/MINECO/RTC-2017-5965-6 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.312 2019 ENGINEERING, ELECTRICAL & ELECTRONIC 35 / 265 = 0.132 2019 Q1 T1 AUTOMATION & CONTROL SYSTEMS 10 / 63 = 0.159 2019 Q1 T1 1.944 2019 Electrical and Electronic Engineering 2019 Q1 Control and Systems Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion 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.
