Dynamic Modeling and Vibration Suppression of Double Flexible Mechanical Arm System

Mechanical arms are widely used in various industrial applications, especially in the field of aerospace and data storage ^[1–2]. Demands of new missions have more stringent requirements than before, and not only dimensions are larger, but also the accuracy. This raises the problem of less accuracy due to vibration of large flexible structures. A great deal of research has been recently focused on vibration suppression ^[3–6]. All of them have their own advantages, but they are difficult to widely used because their additional requirements on the structure and so on. For this problem, works in this article built an accurate model, and then combines it with Component Synthesis Vibration Suppression (CSVS) method ^[7–9]. This method can enhance vibration suppression. Results show there are almost no vibration when the maneuvering stopped.
