Abstract: Based on the inherent characteristic of MR damper with bidirectional adjusting damping force, utilizing the properties of MR damper with bidirectional adjusting damping force with three states of output powers,a medium bang-bang control algorithm and a hierarchical control algorithm of large-span space structures were proposed according to traditional bang-bang control algorithm. A revised clipped-optimal control algorithm of large-span space structures is proposed according to traditional clipped-optimal control algorithm. The control results of different control algorithms were compared and the efficiency of the proposed control algorithms was verified. The controllevels were greatly upgraded.
