摘　　要：为将智能主动杆用于可展结构的自适应控制,研制了一种具有传感和作动双重功能的智能主动杆.对主动杆输出位移、输出力特性以及动力学性能进行了试验研究,获得了不同驱动电压频率的对位移增益和输出力增益.试验结果表明,这类智能主动杆可用于消除铰连接间隙、精确定位和振动抑制.A new type of intelligent active-member with the functions of sensation and actuation was designed and manufactured for the self-adaptive control of deployable structures. The performances of displacement and force outputs of the active-member, as well as its dynamic response, were investigated experimentally, and its displacement and force gains under different frequencies of input voltage were obtained. The experimental results show that the active-member can be used for eliminating joint clearance, precise positioning and suppressing structures vibration.
