SIMULATION AND EXPERIMENTAL STUDY ON ACTIVE CONTROL OF PIEZOELECTRIC STRUCTURE
压电结构的主动控制仿真与实验研究

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.
