Minimum Loop Gain Goal is a constraint on the open-loop gain of the specified control
loop. Thus, the loop gain is computed with the loop open at the specified location. To
compute the gain with loop openings at other points in the control system, use the
Compute response with the following loops open option in the Open-Loop
Response Selection section of the dialog box.


Minimum Loop Gain Goal and Maximum Loop Gain Goal specify only low-gain or high-
gain constraints in certain frequency bands. When you use these requirements, the
software determines the best loop shape near crossover. When the loop shape near
crossover is simple or well understood (such as integral action), you can use “Loop Shape
Goal” on page 10-140 to specify that target loop shape.
