Abstract

This paper presents selective modal space control approach (SMSC) to address the vibration suppression of critical elastic modes of composite cylindrical shell, using collocated/non collocated sensor/actuator. A four node, electro-mechanically coupled field consistent facet shell finite element is used to model the shell vibration. Subsequently, a linear quadratic regulator (LQR) is designed in modal domain to conduct the vibration control simulation studies. The results of active vibration control (AVC) of a laminated composite cylindrical shell, equipped with piezoelectric composite actuators i.e., Macro Fiber Composite (MFC) and PZT sensors are presented. The effectiveness of MFC in controlling shell vibration is evaluated. An effort has been made to addresses the question of whether performance is affected by the collocation/non-collocation of the sensors and actuator.
