About

Fangfang Hu is a robotics and control systems researcher whose work has made meaningful contributions to the modeling and control of flexible robotic systems. Best known for foundational research in the early 1990s on constrained rigid-flexible robot arms, Hu pioneered mathematical frameworks that captured the complex, nonlinear dynamics governing such systems. By employing Galerkin's method to discretize hybrid ordinary-partial differential equations, Hu's 1994 dynamic modeling paper (41 citations) provided a rigorous basis for controller design in flexible robotic arms operating under physical constraints. Complementing this, Hu's work on combined joint motion, vibration, and force control — including the development of a nonlinear modified Corless-Leitmann controller — offered practical solutions to simultaneous regulation and tracking challenges, earning over 30 citations and establishing Hu as a thoughtful contributor to applied control theory. More recently, Hu has extended this expertise into modern optimization techniques, with work on fractional-order PID control for ball-balancing robots using particle swarm optimization, demonstrating a sustained engagement with emerging intelligent control methodologies. Across three decades, Hu's research reflects a consistent commitment to advancing robust, mathematically grounded control strategies for complex robotic systems.
