Abstract |
|
In this paper, an active vibration control model of the three-dimensional (3-D) braided piezoelectric composite beam (BPCB) is developed by using piezoelectric ceramic layers as sensor and actuator. The mechanical parameters of 3-D braided composites with different braided angles and volume fractions are predicted through finite element simulation of a representative volume unit (RVU). Based on Euler–Bernoulli beam theory, the kinematical equation and state space model of the 3-D BPCB are created. The effect of the sensor and the actuator of the 3-D BPCB is discussed. The linear quadratic regulator (LQR) method is adopted as an active control method to analyze the vibration control of the 3-D BPCB, and the optimal weighted matrix is selected by using a genetic algorithm (GA) to evaluate the cost function. Finally, the effect of different braided angles and volume fractions of the 3-D BPCB on the active vibration control is investigated. |
