Inexpensive Experiment for Undergraduates on Active Control of Structural Vibrations.

摘要

The time is rapidly approaching when the United States will launch into Earth orbit highly flexible spacecraft that require control of dynamic deformation as well as the standard control of ridgid body motion. Therefore, engineers involved in research, development, or operation of usch spacecraft should be educated in both of the traditional disciplines of control theory and structural dynamics. Indeed, the interdisciplinary field of control-structure interaction has recently emerged at many universities as a popular field for the conduct of research leading to graduate degrees. Our experience is that the field is accessible also to well-prepared undergraduates. This paper describes a relatively simple and inexpensive experiment in active vibration control that was prepared for (and partly by) USAFA seniors.
