| 摘 要： | 面向航空航天器挠性结构振动主动控制研究背景,针对FXLMS控制算法无法直接从振动结构提取参考信号的缺陷,以经过传感器作动器优化配置的压电机敏柔性梁为模型结构,研究了一种基于多通道FULMS算法的结构振动主动控制器.针对参考信号取自激振信号和直接取自振动结构两种情况,对FXLMS控制算法及FULMS控制算法进行了仿真分析与验证;结果表明FXLMS算法高度依赖参考信号选取,FULMS算法相对FXLMS算法具有更好的收敛性,且能够实现参考信号直接提取策略.在此基础上构建了测控系统和实验平台,进行基于多通道FULMS控制算法的压电柔性结构振动主动控制实验,验证了参考信号从振动结构中直接提取策略的可行性与多通道FULMS控制算法的有效性.

| Abstract: | Facing the background of active vibration control of large flexible space structures,a multi-input multi-output(MIMO)active vibration controller was analyzed and implemented based on filtered-U least mean square(FULMS)algorithm.It could solve the problem that the reference signal of filtered-X least mean square(FXLMS)algorithm can not be extracted from the vibration response of the controlled structure.By analyzing FULMS algorithm and the basic control process briefly,simulations of FXLMS and FULMS algorith... |
