Mr. Decheng Li | Lanzhou University of Technology | China
Dr. Decheng Li, a distinguished scholar at the School of Automation and Electrical Engineering, Lanzhou University of Technology, has made substantial contributions to intelligent control systems, robotics, optimization algorithms, and renewable energy integration. His research consistently bridges theoretical innovation with real-world engineering needs, and his recent work on high-precision optical measurement systems exemplifies this commitment to impactful technological advancement. In the 2025 journal article “Robust hybrid decentralized controller design for Voice Coil Actuator–Fast Steering Mirror (VCA–FSM) system in high-precision optical measurements”, co-authored by Jiabin Liu and Hui Chen and published in Measurement, Dr. Li presents a novel control solution for improving accuracy and stability in fast optical beam steering applications. VCA–FSM systems are critical components in laser communication, adaptive optics, precision imaging, and spaceborne measurement instruments, where rapid response and minimal error are essential. However, these systems often encounter challenges such as parameter uncertainties, external disturbances, nonlinear coupling between axes, and stringent precision requirements. The study introduces a hybrid decentralized control strategy that integrates robust control principles with intelligent algorithmic tuning. This decentralized architecture allows each axis of the FSM to be controlled independently while mitigating cross-axis interference. The hybrid approach combines model-based design with adaptive mechanisms to enhance disturbance rejection and maintain system stability under uncertain conditions. Simulation and experimental results demonstrate that the proposed controller significantly improves tracking accuracy, dynamic response, and robustness compared to conventional centralized or purely model-based controllers. Dr. Li’s contribution not only advances the performance of VCA–FSM platforms but also offers a generalizable framework for other high-precision mechatronic systems. His ongoing work continues to strengthen the integration of automation, intelligent control, and advanced signal processing to achieve next-generation smart engineering solutions.
