Fractional-Order Dynamics and Control of Rigid-Flexible Coupling Space Structures
摘要
The book begins with a brief view of fractional order control strength in modeling and control in this chapter. It is well known that rigid-flexible coupling structures have been widely used in spacecraft with flexible attachments, robotic manipulators and other flexible mechanical/structural systems. The chapter proposes a two-parameter FO model of viscoelastic material and derived the FO dynamics of rigid-flexible coupling structures accordingly to simplify the modeling and controller design for residual vibration suppression. Based on the FO dynamics, a new FO lead-lag compensator design method is proposed to show the power of FO in control community.
