Description

This block is the same as the Check Linear Step Response Characteristics block except

for different default parameter settings in the Bounds tab.

Compute a linear system from a nonlinear Simulink model and plot the linear step

response.

During simulation, the software linearizes the portion of the model between specified

linearization inputs and outputs, and plots the step response 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 step response bounds 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:
