Abstract :
The main manipulator of the spaceborne antenna with multi-configuration has the characteristics of high flexibility and nonlinearity. The dynamic model proposed in this paper is based on multi-body system theory. To realize the goal of rapid deployment and vibration suppression for the main manipulator, variable structure control strategy is adopted. In the control process, different feedback components are used by one switch to realize controlling in phases. At last, the dynamic model and the variable structure control strategy are validated by the experiment.
