When you create a tuning goal in Control System Tuner, a tuning-goal plot is generated.
The dotted line shows the target step response you specify. The solid line is the current
corresponding response of your system.
Creation
In the Tuning tab of Control System Tuner, select New Goal > Rejection of step
disturbance to create a Step Rejection Goal.
Command-Line Equivalent
When tuning control systems at the command line, use TuningGoal.StepRejection to
specify a step response goal.
Step Disturbance Response Selection
Use this section of the dialog box to specify input, output, and loop-opening locations for
evaluating the tuning goal.
- Specify step disturbance inputs
Select one or more signal locations in your model at which to apply the input. To
constrain a SISO response, select a single-valued input signal. For example, to
constrain the step-disturbance response from a location named 'u' to a location
named 'y', click Add signal to list and select 'u'. To constrain a MIMO
response, select multiple signals or a vector-valued signal.- Specify step response outputs
Select one or more signal locations in your model at which to measure the response to
the step disturbance. To constrain a SISO response, select a single-valued output
signal. For example, to constrain the transient response from a location named 'u' to
a location named 'y', click Add signal to list and select 'y'. To constrain a
MIMO response, select multiple signals or a vector-valued signal. For MIMO systems,
the number of outputs must equal the number of outputs.- Compute the response with the following loops open
Select one or more signal locations in your model at which to open a feedback loop for
the purpose of evaluating this tuning goal. The tuning goal is evaluated against the
open-loop configuration created by opening feedback loops at the locations youStep Rejection Goal
