About

H.L. Baek’s research centers on the design and control of ultrasonic motor (USM) drive systems, with a particular focus on high-frequency resonant inverters and fuzzy logic control. Their most cited work, a 2002 study on a fuzzy controller-based resonant inverter for USMs, addresses the critical challenge of precisely regulating motor speed and phase difference to manage the elasticity and viscosity in robotic joints. This contribution is foundational for improving the dexterity and responsiveness of robot manipulators. While the paper has garnered 4 citations, its influence lies in pioneering the integration of intelligent control with power electronics for ultrasonic actuation. Baek’s work is notable for bridging fuzzy logic and resonant inverter design, offering a practical solution for driving traveling wave USMs with two-phase sine wave signals. This research has implications for advanced robotics, particularly in applications requiring fine motion control and adaptive behavior. Baek’s contributions remain relevant for engineers and researchers exploring soft robotics, precision positioning, and smart actuator systems.
