the frequency-domain decomposition (FDD) method in a wireless sensor network for automated mode shape extraction. In this study, a single-input multi-output (SIMO) subspace system identification strategy ideally suited for the decentralized computing architecture of a wireless monitoring system is pro-posed.
It is based on a weighted total least squares approach, starting from multiple input multiple output frequency response functions.
One of the specific advantages of the technique lies in the very stable identification of the system poles as a function of the specified system order, leading to easy-to-interpret stabilization diagrams.
Select Continuous-time or Discrete-time to specify whether the model is a continuous- or discrete-time transfer function. For discrete-time models, the number of poles and zeros refers to the roots of the numerator and denominator polynomials expressed in terms of the lag variable q^ (For discrete-time models only) Specify whether to estimate the model feedthrough.

Frequency Domain Analysis Explained Predicting the future behavior of a process is key to the analysis of feedback control systems. Knowing how the controlled process will react to the controller's efforts allows the controller to choose the course of action required to drive the process variable towards the setpoint.
The true model as well as the disturbances affecting the system are assumed unknown. However, the physical parameters are assumed to enter the coefficients of the system transfer function multilinearly.
A set of models is identified by perturbing the physical parameters one-at-time and using a frequency domain identification technique. Brand new Book.
