Tuning Goals

Specify design requirements for tuning with Control System Tuner

The library of tuning goals in Control System Tuner lets you capture high-level design requirements in a form suitable for fast automated tuning. Use them to specify design objectives such as reference tracking, overshoot, disturbance rejection, or open-loop stability margins. The software tunes the free parameters of the control system to best meet the goals you specify. Use Quick Loop Tuning to tune feedback loops to a target loop bandwidth and stability margin.
