This causes several undesirable phenomena, such as clicking, mechanical wear and contact bounce. Thus, there is great interest in mitigating these switching impacts while keeping the advantageous features of these devices. This paper proposes a complete control strategy for soft landing. The control structure includes three main components. The first one is a real-time flux-tracking feedback controller, which presents several advantages over voltage or current control. The second one is a feedforward controller, which computes the flux reference signal based on a proposed dynamical model and the desired position trajectory for the switching operations. Lastly, the third control component is a learning-type run-to-run adaptation law that iteratively adapts the model parameters based on an audio signal. It exploits the repetitive nature of these devices in order to circumvent modeling discrepancies due to unit-to-unit variability or small changes between operations. The effectiveness of the proposed control is demonstrated through various experiments. info:eu-repo/grantAgreement/EUR/AEI/CPP2021-008938 info:eu-repo/grantAgreement/EUR/AEI/TED2021-130224B-I00 info:eu-repo/grantAgreement/ES/DGA/T45-20R info:eu-repo/grantAgreement/ES/MICINN-AEI-FEDER/PID2021-124137OB-I00 info:eu-repo/grantAgreement/ES/MICINN-AEI/RTC-2017-5965-6 info:eu-repo/grantAgreement/ES/MICINN/PGC2018-098719-B-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 7.5 2023 AUTOMATION & CONTROL SYSTEMS 6 / 84 = 0.071 2023 Q1 T1 INSTRUMENTS & INSTRUMENTATION 2 / 76 = 0.026 2023 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 25 / 353 = 0.071 2023 Q1 T1 3.395 2023 Electrical and Electronic Engineering 2023 Q1 Control and Systems Engineering 2023 Q1 Computer Science Applications 2023 Q1 16.8 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Ramírez-Laboreo, Edgar Universidad de Zaragoza (orcid)0000-0002-8977-5296 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.
