Step Rejection Goal
Purpose
Set a minimum standard for rejecting step disturbances, when using Control System
Tuner.Description
Use Step Rejection Goal to specify how a step disturbance injected at a specified
location in your control system affects the signal at a specified output location.You can specify the desired response in time-domain terms of peak value, settling time,
and damping ratio. Control System Tuner attempts to make the actual rejection at least as
good as the desired response. Alternatively, you can specify the response as a stable
reference model having DC-gain. In that case, the tuning goal is to reject the disturbance
as well as or better than the reference model.To specify disturbance rejection in terms of a frequency-domain attenuation profile, use
Disturbance Rejection Goal.10 Control System Tuning
