Flexible structures with surface bounded or embedded piezoelectric ceramic patches have received much attention in active vibration control of structures in recent years. The paper studies the Hinfin robust active control strategy of the vibration system for the flexible cantilever beam. The model of the system is built by the application of ANSYS software, and then the vibration model is gained by...
Based on the linear quadratic Gauss (LQG) optimal control method, the paper introduces an effective procedure to suppress the vibration of flexible structures with the sensors/actuators are symmetrically collocated on both sides of the same position on the host structure. The model of a piezoelectric intelligent cantilever beam is built by the application of ANSYS software. The D-optimal design principle...
Piezoelectric materials are finding increasing applications in active vibration control of structures. A widely used modeling technique for piezoelectric flexible structures is the assumed modes method which results in an infinite dimensional model of the composite structure. The paper builds the model of piezoelectric flexible structures and calculates the modal frequency by the application of ANSYS...
