摘　　要：自适应桁架中的测控技术涉及传感器、驱动器、信号信息处理单元及通信技术等多项关键技术。本研究针对空间柔性自适应桁架结构制作了实验模型,在其上布置压电传感器和作动器,借助测控系统平台,采用改进的二次积分力反馈控制方法研究了空间柔性自适应桁架结构的振动主动控制问题。实验研究表明该控制方法行之有效。The measurement and control technology applied in self-adaptive truss structure is related to sensor, actuator and information processing technology and communication technology. Several sensors and actuators are applied to spatial flexible self-adaptive truss structure which is developed. With an improved integral plus double integral force feedback method,the active vibration control of spatial flexible self-adaptive truss structure by using measurement and control system is studied.The experiment results show that control strategy is correct and effective.
