Tuning Goals

Specify design requirements for command-line tuning

The library of tuning goals lets you capture high-level design requirements in a form suitable for fast automated tuning. TuningGoal objects let you specify design objectives such as reference tracking, overshoot, disturbance rejection, or open-loop stability margins. Use the TuningGoal objects as input arguments to systune to enforce them as constraints (hard goals) or objectives (soft goals). The software tunes the free parameters of the control system to best meet the goals you specify.
