Piezoelectric stack sensor/actuator (PSSA) is one of the most important elements of the piezoelectric intelligent active member, which is an electromechanical coupling system.

Optimal placement of active members for vibration active control of intelligent space truss structures via Genetic Algorithms is discussed in the paper.

The objective of this paper is to study the method and effectiveness of using active members to realize active damping control of adaptive truss structures.

This work intended to introduce an integrated piezoelectric smart active member;its actuator and sensor were composed of a few piezoelectric elements.

A new kind of piezoelectric active member, which can be used to control the elastic vibration of space flexible structure,was developed based on the converse piezoelectric effects of piezoelectric ceramic material.

A new kind of in line piezoelectric active member is developed based on the actuation effect of piezoelectric material in this paper,which can be used as a major component of intelligent truss structure.

This paper presents the results of active damping realized by a piezoelectric active member to control the vibration of a four-bay four-longern aluminum truss structure with cantilever boundary.
