PARAMETER IDENTIFICATION OF FLEXIBLE PLATE BASED ON THE ACCELERATION OUTPUT

  • 摘要: 以柔性板为对象,开展了结构挠性参数辨识技术的研究. 给出了一种基于加速度信号输出的特征系统实现算法的计算格式,基于粒子群优化算法给出了加速度传感器在柔性板上的优化位置. 仿真结果显示,粒子群方法能够有效地确定出传感器在板上的优化位置,特征系统实现算法能够有效地辨识出结构的挠性参数.

     

    Abstract: This paper studies the parameter identification using a flexible plate as research object. An eigensystem realization algorithm (ERA) based on the output of acceleration sensors is investigated and the optimal positions of sensors on the plate are studied using the particle swarm optimization (PSO). Simulation results indicate that the PSO may effectively determine the optimal positions of sensors on the plate, and the plate parameter may be identified accurately using the ERA.
