Sensitivity Goal
Purpose
Limit sensitivity of feedback loops to disturbances, when using Control System Tuner.Description
Sensitivity Goal limits the sensitivity of a feedback loop to disturbances. You specify the
maximum sensitivity as a function of frequency. Constrain the sensitivity to be smaller
than one at frequencies where you need good disturbance rejection.To specify a Sensitivity Goal, you specify one or more locations at which to limit
sensitivity. You also provide the frequency-dependent maximum sensitivity as a numeric
LTI model whose magnitude represents the desired sensitivity as a function of frequency.When you create a tuning goal in Control System Tuner, a tuning-goal plot is generated.
The dotted line shows the gain profile you specify. The shaded area on the plot represents
the region in the frequency domain where the tuning goal is not satisfied.Sensitivity Goal
