Analysis Point Description

Loop transfer
function

Specifies an output measurement before a loop break followed by an

input perturbation.

To compute the open-loop transfer function around a loop, use a loop

transfer analysis point.

For example, to compute -KG in the example system, specify the loop

transfer analysis point as shown. The software adds an output

measurement u breaks the signal flow, and adds an input perturbation

du.
