一种新型自感知作动器及其应用

A Self-sensing Actuator and Its Usage in Active Control

利用压电片的正逆压电效应,提出了一种基于分时结构的自感知作动器,将压电片作为传感器和作动器的功能在时间上进行分离,以实现用同一压电片在作动与传感之间的功能切换,并探讨了其用于主动控制的可行性。对一悬臂梁的振动主动控制研究表明该自感知作动器在实际上是可行的。

By applying PZTs piezoeffect and piezoelectric converse effect,a new type of selfsensing actuator based on timesharing was presented,which can switch between sensor and actuator.Thus,different performances are realized with only one PZT patch.Further,a experiment was set up to test the practicability and the results of experiment prove the validity.
