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。实验研究了主动杆输出位移、输出力特性以及动力学性能,对位移增益和输出力增益随驱动电压的变化进行了测试。实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 active-member with functionsof sensation and actuation was designed andmanufactured which could be used to adaptively controland improve performance of deployable structures. Theperformances of displacement and force outputs,as well as dynamic response, of the active-member were experimented, and displacementand force gains of the member at differentfrequencies of input voltages were obtained.The experimental results show that the active-member can be used for eliminating the jointclearances, positioning precisely, andsuppressing vibrations of deployablestructures.
