About

Motonobu Aoki is a control systems researcher whose work focuses on robust resonance suppression for robotic applications, particularly humanoid robots. His key research areas include two-inertia system modeling, disturbance observer design, and vibration control in flexible transmission systems. Aoki’s major contribution is the development of the Self Resonance Cancellation Disturbance Observer (SRCDOB), a novel control framework that enhances robustness against modeling errors and external disturbances while suppressing mechanical resonance. His most cited paper, “Robust resonance suppression control based on self resonance cancellation disturbance observer and application to humanoid robot” (2013), has accumulated 17 citations and demonstrates the practical application of his method to humanoid platforms. Aoki’s work addresses a critical challenge in high-performance robotics: the need to maintain stability and precision despite the spring-like dynamics introduced by lightweight, flexible transmissions. By integrating self resonance cancellation control with a disturbance observer, he provides a solution that is both theoretically sound and experimentally validated. His research has implications for advanced humanoid robots requiring smooth, accurate motion under uncertain operating conditions.
