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...
Considerable attentions have been devoted recently to active vibration control using intelligent materials as sensors/actuators. This paper presents results on active control schemes for vibration suppression of flexible cantilever beam with bonded piezoelectric sensors and actuators. State equations which the generalized modal coordinates as variables are built. With the piezoelectric elements are...
This paper demonstrates an active vibration control system of flexible structures by using piezoelectric sensors and actuators. A set of vibration control equations, sensing equations and actuating equations are derived through using the modal theory for piezoelectric flexible structures, then the model is converted into the state space form. With recent developments in sensors/actuators technologies,...
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...
