Step Tracking Goal


Purpose


Make the step response from specified inputs to specified outputs closely match a target
response, when using Control System Tuner.

Description


Step Tracking Goal constrains the step response between the specified signal locations to
match the step response of a stable reference system. The constraint is satisfied when the
relative difference between the tuned and target responses falls within the tolerance you
specify. You can use this goal to constrain a SISO or MIMO response of your control
system.

You can specify the reference system for the target step response in terms of first-order
system characteristics (time constant) or second-order system characteristics (natural
frequency and percent overshoot). Alternatively, you can specify a custom reference
system as a numeric LTI model.
