About

Dr. Zhen Qi has made significant contributions to the field of robotics, specializing in the control and visual servoing of parallel robots. His research focuses on developing advanced control strategies to enhance the precision and stability of these complex mechanical systems. Dr. Qi's most impactful work, "Trajectory Tracking with Parallel Robots Using Low Chattering, Fuzzy Sliding Mode Controller" (2006), has garnered 51 citations, demonstrating its influence in addressing the critical challenge of reducing chattering in sliding mode control—a common issue that degrades performance and causes wear. He further advanced the field by integrating computer vision with parallel robot control, as seen in his 2008 paper on "Improved Image Based Visual Servoing with Parallel Robot" (14 citations). Notably, his 2007 work on "Nonlinear Image Based Visual Servoing Using Parallel Robots" (9 citations) tackled the control problem of an eye-in-hand parallel robot based precision pointing system, where the visual sensor is mounted directly on the robot platform. This research aimed to precisely move the platform so that image feature points align with desired positions, a critical capability for high-precision applications. Through these contributions, Dr. Qi has advanced the practical deployment of parallel robots in tasks requiring both robust control and visual feedback.
