Simulink Control Design™ - MathWorks

Creation

In the Tuning tab of Control System Tuner, select New Goal > Maximum overshoot to

create an Overshoot Goal.

Command-Line Equivalent

When tuning control systems at the command line, use TuningGoal.Overshoot to

specify a step response goal.

Response Selection

Use this section of the dialog box to specify input, output, and loop-opening locations for

evaluating the tuning goal.

• Specify step-response inputs

Select one or more signal locations in your model at which to apply the step input. To

constrain a SISO response, select a single-valued input signal. For example, to

constrain the step 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 input. To constrain a SISO response, select a single-valued output signal. For

example, to constrain the step 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.

• Evaluate overshoot 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 you

identify. For example, to evaluate the tuning goal with an opening at a location named

'x', click Add signal to list and select 'x'.
