    Position Control of a Maglev System Fed by a DC/DC Buck Power Electronic Converter by Victor Manuel Hernández-Guzmán, Ramón Silva-Ortigoza, Magdalena Marciano-Melchor

    Published 2020-01-01
    “…In this respect, we stress that most works in the literature on control of electromechanical systems actuated by power electronic converters are devoted to control brushed DC motors which are well known to have a linear model. Furthermore, despite the plant that we control in the present paper is complex, our control law is simple. …”

    Bottom Detection Method of Side-Scan Sonar Image for AUV Missions by Huapeng Yu, Ziyuan Li, Dailin Li, Tongsheng Shen

    Published 2020-01-01
    “…In order to obtain the measurement parameters of the sea bottom geomorphology or underwater objects, the first step in side-scan sonar (SSS) image processing is bottom detection. Due to the complexity of the marine environment, the acoustic signals received by SSS are usually polluted by noises, which affect its image quality and make the extraction of image features difficult. …”
