About

Nam Duc is a leading researcher in the field of bilateral teleoperation and cooperative robotics, with a focus on overcoming the challenges of time-varying communication delays. His work centers on developing advanced control architectures—including passive decomposition, impedance control, and force-reflection (FR) algorithms—to enhance stability, transparency, and tracking performance in teleoperation systems. Duc’s most cited paper, “Multiple Cooperative Bilateral Teleoperation with Time-Varying Delay” (2011, 9 citations), introduces a novel passive-decomposition approach that enables a single master robot to control multiple cooperative slave robots, effectively decoupling their dynamics for improved coordination. His earlier work, “Impedance control for force-Reflecting teleoperation with communication delays based on IOS small gain theorem” (2009, 8 citations), proposes a force-reflection scheme that leverages an additional communication channel to boost tracking fidelity. Duc’s contributions are further solidified by his four-channel force-reflection framework (2010, 7 citations) and his extension of input-to-state stability (ISS) small-gain theorem to cooperative multi-slave systems (2011, 4 citations). Through these innovations, Duc has advanced the theoretical and practical foundations of teleoperation, enabling more reliable and responsive robotic control in applications ranging from remote surgery to hazardous environment manipulation.
