High-performance Interaction Force Control utilizing Various Sensors
Wednesday 22 November 2023 at 9:00 PM KST (1:00 PM CET, 7:00 AM EST) By Sehoon Oh (DGIST, Daegu, South Korea) Register now using the link below: https://attendee.gotowebinar.com/register/2192665213917476958 Abstract: Mechatronic systems, recently, are required to interact with humans/environments not only in a safe way but also achieving desired tasks. However, the interaction with humans/environments is a demanding task in terms of actuation, since the interaction involves feedback loops that are frequently unknown. To address this issue, the mechatronic system makes use of interaction force sensing and devises various interaction force controllers. Force sensors (such as strain gauge type) and elastic parts (such as springs) are widely utilized to measure the interaction force, and those sensors have their advantages and drawbacks. In this webinar, a comprehensive view of these interaction force controls is provided: the type of desired interactions, the type of interaction force sensing as well as the design methodologies of force controllers. The difficulty of the interaction force control is discussed theoretically, and the controller designs to attack this problem are discussed. Lastly, the applications to the motor system as well as the robotic system are explained. Presenter’s bio: Sehoon Oh received the B.S., M.S., and Ph.D. degrees ...

Static and Dynamic Wireless Power Transfer with Wide-Range Output and High Efficiency
Friday 24 November 2023 at 8:00 PM CST (1:00 PM CET, 7:00 AM EST) By Zhicong Huang (Shien-Ming Wu School of Intelligent Engineering at South China University of Technology, China) Register now using the link below: https://attendee.gotowebinar.com/register/3765967397218157911 Abstract: Wireless power transfer (WPT) via magnetic coupling can have both the transmitter and receiver insulated and contactless, and thus shows versatility in both static and dynamic WPT applications under hostile environments where a physical connection is inconvenient or impossible. However, as a high-order resonant converter, it is challenging for a WPT converter to achieve wide-range outputs while maintaining high efficiency. This tutorial starts with this challenging issue, followed by an efficiency optimization principle and several methods for simultaneously achieving wide-range outputs and good efficiency. These methods will share ideas of load-independent-transfer characteristics, linear transfer functions, active rectification, active compensation, and so on. A thorough introduction to these methods will be provided with an emphasis on the achievement of stable output regulation and maximum efficiency tracking against variations of coupling coefficient and load condition, which typically occur in dynamic WPT application scenarios. This tutorial will touch on the topic of development for a wireless interface for future grid-to-vehicle and vehicle-to-grid operations. A ...
