Abstract:The power flow active control and vibration energy propagation of crossing-shaped plate with simply support boundary conditions using piezoelectric patch as actuators are studied. The combination of modal method and traveling wave method is employed to obtain the accurate analytical solution. The feedforward filtered-X least mean square (LMS) algorithm is used to obtain the optimal control moment for minimizing the power flow propagation in the plate structures. The results have shown that the vibration energy… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
