提出了一种新的有效的系统辨识方法，用于确定未知结构系统的模型结构和参数估计，以产生多输入多输出（MIMO）模型。没有先验知识的非线性假设。当系统包含集中质量时，所有关于连接系统中集中质量的线性和非线性连杆的位置、类型和系数的信息可以在一个有效的过程中确定。新算法产生了一个简约的连续时间模型，这对于在实际应用中解释系统很有用。最后通过算例验证了该方法的有效性。
A new efficient system identification method is introduced to determine the model structure and parameter estimates of an unknown structural system to produce a multi-input multi-output (MIMO) model. No a priori knowledge is assumed regarding the nonlinearities. When the system involves lumped masses, all the information about the locations, types, and coefficients of both linear and nonlinear links which connect the lumped masses in the system can be determined in one efficient procedure. The new algorithm yields a parsimonious continuous time model which is useful for the interpretation of the system in practical applications. An illustrative example demonstrates the efficiency of the new method.
