This article is the first in a series of lectures. Aimed at the problem of vibration control of complex structures in engineering, this paper takes a typical aerospace structure as an example to introduce the basic concepts of vibration control integration theory and technology to solve the problem of vibration control technology in complex structure. Various vibration control strategies, control materials and devices were discussed and compared, and the problems encountered in the implementation of vibration control integration strategy were analyzed, including robust control in control law, optimization of actuators and sensors Configuration problems, the application of smart materials in vibration control, with particular emphasis on the important role of hybrid damping in structural vibration reduction. The control mechanism, optimization design and intelligent structure development and research objectives are discussed. It is pointed out that the research of vibration control must be combined with the specific engineering problems. The importance of the experiment should be emphasized. It is suggested that a standardized verification model of cooperative research be established to promote the theory of vibration control integration Technology development.
