| Abstract: | In order to study the dynamics characteristics and
capabilities of piezoelectric smart structures, the Negative Velocity
Feedback Control and Modal Space Control technique based on Linear
Quadratic Regulator (LQR) control are used together with Finite Element
Method in this paper. A new method of numerical simulation
using PATRAN/NASTRAN and MATLAB is adopted to control the vibration of
structures. Vibration control experiment of a plate shows the validity of the
new simulation method with MATLAB/xPC Real-Time Workshop.
Results show that the control method by using piezoelectric material is
effective. |
