摘要
提出了一个用于压电智能结构振动控制的模态控制方法。就智能梁给出了压电模态传感器与压电模态致动器的新设计方法以及相应的模态控制方法，并对相应的观测溢出与控制溢出问题进行了分析，给出了抑制这些溢出的措施。
A new modal control scheme,distributed piezoelectric segment method, for smart structures with piezoelectric sensor and actuator layers is presented. The corresponding modal sensor and modal actuator design methods are given and the related spillover problems are also analyzed.Thre are three advanteges to this method:changing the order of controlled modes can be realized by software; it may not be necessary to change the senor and actuator laminate for a change in the basic structure; the sensor/actuator can sence/actuate not only the local strain but also the entice strain.
