Model Verification

Verify time- and frequency-domain characteristics of linearized models against specified bounds, verify subsystems

Simulink® Control Design™ software provides Model Verification blocks to monitor time-domain and frequency-domain characteristics of a linear system computed from a nonlinear Simulink model during simulation. You can use these blocks to define bounds on specific linear system characteristics and check whether these bounds are satisfied during simulation. For more information, see Monitor Linear System Characteristics in Simulink Models and Verifiable Linear System Characteristics.

Topics

Monitor Linear System Characteristics in Simulink Models

Monitor time-domain and frequency-domain characteristics of linear systems computed from nonlinear Simulink models during simulation.

Define Linear System for Model Verification Blocks

To compute a linear system for model verification, specify linearization inputs, linearization outputs, and when to linearize the model.

Verifiable Linear System Characteristics

You can specify bounds on time-domain and frequency-domain linear system characteristics, and assert that the bounds are satisfied during simulation.

Verify Model at Default Simulation Snapshot Time

Assert that bounds on the linear system characteristics of a nonlinear Simulink model are satisfied at the start of the simulation.

Verify Model at Multiple Simulation Snapshots

Assert that bounds on the linear system characteristics of a nonlinear Simulink model are satisfied at multiple snapshot times.

Verify Model Using Simulink Control Design and Simulink Verification Blocks

Assert that linear system characteristics satisfy specified bounds using a combination of Simulink Control Design and Simulink verification blocks.
