挠性智能梁的可镇定性

Stability of a Flexible Smart Beam

研究采用共位配置的分布式压电敏感器和致动器的挠性悬臂梁的可镇定性问题，给出两种敏感器和致动器分布函数的表达式，并验证它们满足系统可镇定的条件。证明了在其中之一的一种分布函数下，闭环系统是指数稳定的。

This paper is concerned with the stability of a flexible cantilever beam with collocated piezoelectric sensors and actuators. Two kinds of the expression of the distribution function of the sensors and actuators are presented and shown to satisfy the stability conditions of the system. Furthermore, it is shown that for one of the two cases, the closed-loop system is exponentially stable.
