Abstract


With the rapid development of aerospace technology, large-scale, low stiffness and flexibility of an important development trend of the various types of aerospace structures, flexible component is more and more popular, the elastic deformation of the flexible component vibration problem has been research the focus of the problem. In this paper, the flexible beam for the study, a systematic theoretical and experimental study of the use of piezoelectric ceramics inverse piezoelectric effect of active vibration control of flexible beam. First chapter, an overview of the thesis research background and significance, from the theoretical modeling of the flexible component, classify vibration control, active vibration control law of smart materials and smart materials actuator and sensor flexible component vibration active control Research Summary Finally expounded the main contents of this article. The second chapter, the vibration of the flexible beam dynamics analysis to establish a flexible beam bending vibration dynamics differential equations. Elaborate on the piezoelectric material of the piezoelectric equations and piezoelectric applications, the piezoelectric equations deduced moment Equation piezoelectric actuator. Combined resistance strain sensor principle and mechanics of materials derived resistance strain sensor output equation. Finally, integrated piezoelectric actuator moment equation, the sensor output equation as well as the flexible beam dynamics differential equations, state space expression piezoelectric flexible beam. Chapter III, on the important issues - actuator / sensor optimized piezoelectric flexible beam vibration control configuration. Expression combined with the state of the the second chapter piezoelectric flexible beam space, were selected to the minimum energy input and maximum sensor signal energy as their configuration optimization criterion for actuator and sensor, and the introduction of genetic algorithms as optimization calculation method, the use of The genetic algorithm optimized actuator / sensor location configuration. Finally, numerical optimization simulations to determine the optimal configuration of the actuator / sensor, actuator / sensor configuration to another location to numerical simulation, and the simulation results of a comparative study. Chapter 4, the piezoelectric active vibration control of flexible beam control law. Elaborate linear quadratic optimal control theory principles, and applied to the piezoelectric flexible beam using MATLAB simulation environment vibration control simulation results prove the linear quadratic optimal control system while simulation results also verify that the third chapter of the correctness of the actuator / sensor location optimization configuration. Chapter 5, the formation of the piezoelectric flexible beam vibration active control experiment platform, expounded on the experimental system of hardware, software, experimental study of the control law designed by the Chapter, through experimental results further validate the actuator / sensor location Optimized Configuration and linear quadratic optimal control theory application correctness. Chapter summarized, and the future prospect of the full text.
