Batch Trim Model at Known States Derived from Parameter

Values

This example shows how to batch trim a model when the specified parameter variations

affect the known states for trimming.

In the “Batch Trim Model for Parameter Variations” on page 1-99 example, the model is

trimmed to meet a single operating point specification that contains unknown states. In

other cases, the model states are known for trimming, but depend on the values of the

varying parameters. In this case, you cannot batch trim the model using a single

operating point specification. You must create a separate specification for each parameter

value grid point.

Open the Simulink model.

sys = 'scdairframeTRIM';

open_system(sys)

In this model, the aerodynamic forces and moments depend on the speed, , and

incidence,.

Vary the and parameters, and create a 6-by-4 parameter grid.
