Analysis Point Description

Open-loop

output

Specifies an output measurement followed by a loop break.

To linearize a plant or controller, you can use an open-loop output with

an input perturbation or an open-loop input.

For example, to compute the response -K in the example system, add

an open-loop output after K and an input perturbation dy after G, as

shown. The open-loop output breaks the signal flow and adds an

output measurement u.
