This paper is the first one of the series lectures on《passive and active integrated vibration control theory and technology》. To the vibration control problem of a complex structure in the engineering, taking a typical aerospace structure as a example, the basic concept of integrated vibration control was introduced, so that the problem how to realize the vibration control technology about complex structure was settled. Aiming at how to realize the vibration control integrated strategy problems, the discussion and comparison are done about the kinds of vibration control strategies, the control material and the apparatus. The analysis is put up, which include robust control of law, optimize configuration of sensors and actuators, and the applications of the smart material in the vibration control. Specially, the important role of the hybrid damping in the structure vibration suppression is emphasized. Probing into the control mechanism, optimize design, the future development and study target of smart structure are described. From above the conclusions will be got that the study of vibration control should be combined with the real engineering issue. The importance of experiment study will be emphasized. And some standardization validate model should be suggestion to set up for cooperative study. At last, the development of vibration control integrated theory and technology will be got advancement.
