PROBLEM DEFINITION The study on the control of a ﬂexible arm manipulator started as a part of the space robots passive damp- ing augmentation to active control of a large ﬂexible space manipulator. [361] used the concept of reducing vibration in the ﬂexible structure internal [11], Wang [380], Wang and Russel [382,383], Kumar et al. of future space missions necessitate advances in the control of large flexible structures. These structures will be extremely flexible, with little natural damping and modes which are densely packed through- out the frequency domain. Due to their size and complexity, ground testing of these structures in Earth s environment will lead to system The paper focuses on the design and nonlinear control of the humanoid wrist/shoulder joint based on the cable-driven parallel mechanism which can realize roll and pitch movement. In view of the existence of the flexible parts in the mechanism, it is necessary to solve the vibration control of the flexible wrist/shoulder joint. In this paper, a cable-driven parallel robot platform is control of large flexible space structures (LFSS) using smart materiais.
