摘　　要：研究了挠性结构主动振动控制系统中执行机构的配置与系统可控性的关系,针对可以简化为梁结构的挠性结构,分析了为了保证系统可控性所需要配置的执行机构的具体数目,得到了定量的结论。This paper discusses the relationship between actuator assignment and system con-trollability in the active vibration control system of flexible structures. For a class of flexible structures which can be simplified to girder structures, the actual number of actuators to be as-signmented in the flexible girder that can guarantee controllability of the active control system is analyzed, and a quantitative conclusion is formulated.
