Description

This block is the same as the Singular Value Plot block except for default parameter

settings in the Bounds tab:

Check that upper and lower bounds on singular values of a linear system, computed from

a nonlinear Simulink model, are satisfied during simulation.

The Simulink model can be continuous-time, discrete-time or multirate and can have time

delays. The computed linear system can be single-input single-output (SISO) or multi-

input multi-output (MIMO).

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

linearization input and output, computes the singular values, and checks that the values

satisfy the specified bounds:

• 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:
  
  
  • Evaluate a MATLAB expression.
  
  
  • Stop the simulation and bring that block into focus.
