About

Dr. Weijie Sun is a leading researcher in control theory and nonlinear systems, with a focus on formation control and disturbance rejection. His most influential work, "Leader-follower formation control without leader’s velocity information" (2014), has garnered 25 citations, pioneering methods for multi-agent systems to maintain formation without requiring direct velocity data from a leader—a critical advancement for autonomous vehicles and robotics. Dr. Sun’s earlier contribution, "High Gain Disturbance Observer-Based Control for Nonlinear Affine Systems" (2012), introduced a novel high-gain disturbance observer that accommodates a broader class of disturbances generated by nonlinear exo-systems, significantly expanding the applicability of disturbance rejection techniques. By employing a two-stage design framework, this work enhanced robustness in complex, real-world environments. Dr. Sun’s research bridges theoretical rigor and practical implementation, offering scalable solutions for networked systems. His achievements have established him as a key figure in advancing observer-based control and formation strategies, inspiring further exploration in autonomous coordination and disturbance mitigation.
