Validate Operating Point Against Specifications

When you compute an operating point based on input, output, or state specifications, the

Simulink Control Design software indicates whether the specifications were successfully

met during the trimming process. If the trimming was unsuccessful, to determine the

specifications that could not be met, you must validate your trimmed operating point

against the original specifications.

Validate Operating Point in Steady State Manager

When you compute an operating point using Steady State Manager, the software

creates an operating point report object and highlights any operating point values that

violate the constraints in the specification.

For example, consider the scdairframeTRIM model. Open the model and set the speed

and incidence angle parameters.

sys = 'scdairframeTRIM';

open_system(sys)

alpha_ini = -0.21;

v_ini = 933;

To open Steady State Manager, in the Simulink model window, select Analysis >

Control Design > Steady State Manager.

Create a trim specification for the model. On the Steady State tab, click Trim

Specification.

In the spec1 document, specify which states are known and which are at steady state.
