Manage Tuning Goals
Control System Tuner lets you designate one or more tuning goals as hard goals. This
designation gives you a way to differentiate must-have goals from nice-to-have goals.
Control System Tuner attempts to satisfy hard requirements by driving their associated
cost functions below 1. Subject to that constraint, the software comes as close as possible
to satisfying remaining (soft) requirements. For best results, make sure you can obtain a
reasonable design with all goals treated as soft goals before attempting to enforce any
goal as a hard constraint.By default, new goals are designated soft goals. In the Tuning tab, click Manage
Goals to open the Manage tuning goals dialog box. Check Hard for any goal to
designate it a hard goal.You can also designate any tuning goal as inactive for tuning. In this case the software
ignores the tuning goal entirely. Use this dialog box to select which tuning goals are
active when you tune the control system. Active is checked by default for any new goals.
Uncheck Active for any design goal that you do not want enforced.For example, if you tune with the following configuration, Control System Tuner optimizes
StepRespGoal1, subject to MarginsGoal1. The tuning goal PolesGoal1 is ignored.Manage Tuning Goals
