UESTC Robotics Research Center Student Honored with Best Oral Presentation Award at ICoCTA 2025

Recently, the 5th International Conference on Control Theory and Applications (ICoCTA 2025) was successfully held in Chengdu, China. The conference was technically co-sponsored by IEEE and the IEEE Chengdu Section, hosted by Southwest Jiaotong University, and co-organized by the University of Electronic Science and Technology of China and Xi'an Jiaotong University, bringing together renowned experts, scholars, and young researchers from around the world in the field of control theory and engineering.

At this conference, Hao Lin, an undergraduate student from the School of Automation Engineering supervised by Associate Professor Peng Zhinan at the center, delivered an oral presentation on her paper titled "Observer-Identifier-Based Optimal Control of Nonlinear Systems with Unknown States and Dynamics" and was honored with the "Best Oral Presentation Award."

The research focuses on the optimal control problem of nonlinear systems and addresses the complex scenario where both system states and dynamic models are unknown, proposing an Observer-Identifier-based Optimal Control (OIOC) framework. This method integrates a neural network observer, DREM parameter identification technology, and a critic neural network to achieve a unified design of state estimation, system identification, and control law optimization. Compared with traditional adaptive dynamic programming methods that rely on gradient descent and strict persistent excitation (PE) conditions, this framework ensures the convergence of parameters and weights as well as closed-loop system stability under relaxed excitation conditions. Theoretical analysis and numerical simulations both demonstrate that the method maintains good learning performance and stable control effectiveness even under limited excitation conditions, providing a new approach for the adaptive optimization of intelligent control systems.

Upon receiving the award certificate, Hao Lin expressed her gratitude: "Being able to present our research at an international conference and receive this honor would not have been possible without the meticulous guidance and strict requirements of Professor Peng Zhinan. Professor Peng not only provided me with profound inspiration in theoretical derivation and experimental design but also had a significant impact on my research thinking, academic standards, and innovative spirit. The success of this presentation is an important step in my personal growth and a reflection of the center's research atmosphere and the effectiveness of its mentorship system."

As an important international academic platform in the IEEE control field, the ICoCTA conference aims to promote the latest advances and interdisciplinary integration in control theory and its applications. This award not only showcases the research strength of our university's Robotics Research Center in the direction of intelligent control and adaptive systems but also fully reflects the active exploration and outstanding performance of undergraduate students in scientific research innovation.

In the future, the center team will continue to focus on the interdisciplinary intersection of artificial intelligence and control theory, conducting in-depth research on adaptive intelligent control, human-robot interactive shared control for robotic systems, and other areas, to promote the output and practical application of high-level scientific research achievements.
