Pole-Zero Analysis

Computes a pole-zero plot for a system model. This step computes the locations and confidence areas of the zeros and poles for one input-output pair of a system model.

ParameterDescription
Pole-Zero PlotDisplays the pole-zero plot of the system model.
Input ModelContains the following option:
  • Model—Specifies the estimated model to use for pole-zero analysis.
ConfigurationContains the following options:
  • Input source—Specifies the input source type to compute the transfer function. You can select stimulus or noise.
  • Graph Settings—Contains the following option:
    • Confidence level—Specifies the confidence area of the pole-zero location. The confidence radius equals confidence level times the standard deviations of the FRF. The default is 99%.
