提出利用模型参考自适应辨识器的原理来识别机械振动系统的质量矩阵、刚度矩阵和阻尼矩阵;设计了适用于线性定常机械振动系统的串并联辨识器;分析了该辨识器的稳定性和收敛性条件;最后通过一个简单的例子说明了辨识器的设计步骤。
The principle of model reference adaptive recognizer is proposed to identify the mass matrix, stiffness matrix and damping matrix of a mechanical vibration system. A series-parallel recognizer which is suitable for linear stationary mechanical vibration system is designed. The stability and convergence of the recognizer are analyzed. Finally, a simple example is given to illustrate the design steps of the recognizer.
