Pole-Zero Plot


Pole-zero plot of linear system approximated from nonlinear Simulink model

Description


This block is the same as the Check Pole-Zero Characteristics block except for different
default parameter settings in the Bounds tab.

Compute a linear system from a Simulink model and plot the poles and zeros on a pole-
zero map.

During simulation, the software linearizes the portion of the model between specified
linearization inputs and outputs, and plots the poles and zeros of the linear system.

The Simulink model can be continuous- or discrete-time or multirate and can have time
delays. Because you can specify only one linearization input/output pair in this block, the
linear system is Single-Input Single-Output (SISO).

You can specify multiple bounds that approximate second-order characteristics on the
pole locations and view them on the plot. You can also check that the bounds are satisfied
during simulation:


  • If all bounds are satisfied, the block does nothing.

  • If a bound is not satisfied, the block asserts, and a warning message appears at the
    MATLAB prompt. You can also specify that the block:
