英文摘要: In this project, the study is focused on the vibration control for axially moving system with high acceleration of precision electronic manufacturing equipment. Based on active vibration control idea and online/offline combined control scheme, robust adaptive boundary control algorithm combining with intelligent control technology is developed for governing the vibrations of axially moving system, and the theory and method of active vibration control are successfully applied to the precision electronics manufacturing equipment. The detail research content as following: 1)The dynamic model which characterized the structural vibration can be developed after dynamic analysis and geometric nonlinear characteristics analysis of axially moving system. 2) The high real-time control scheme aslo can be achieved after considering all aspects of requirements, such as control function, control algorithm and work time. 3) Robust adaptive boundary control algorithm combining with intelligent control technology is developed which control design are based on the original infinite dimensional partial differential equation. The spillover phenomenon is avoided. Theoretical analysis and mathematical proof for stability of axially moving system will be carried out. 4) In our SMT design platform, the proposed robust adaptive boundary
