Check Linear Performance
In addition to examining linear responses associated with tuning goals, check other linear
responses of the system to make sure that the behavior is suitable. You can do so by
extracting and plotting system responses as described generally in “Validate Tuned
Control System” on page 10-225.
For gain-scheduled systems, it is good practice to check linear performance on a denser
grid of operating points than you used for design. If the system does not maintain
adequate linear performance between design points, then you can add more design points
and retune.
