Robust Controller Tuning

Achieve robust performance for uncertain or changing plants

The systune command and Control System Tuner app can tune control systems to design requirements you specify, while taking into account system variability and model uncertainty to achieve robust performance. You can tune controllers to maximize performance over a range of values for the plant parameters. You can also simultaneously tune for multiple plant models or control configurations. For information about these different approaches to robust tuning, see Robust Tuning Approaches.

Functions

Topics

Robust Tuning Basics

Robust Tuning Approaches
The Robust Control Toolbox™ tuning tools let you tune control systems for robustness against plant variation, or to accommodate uncertainty in physical parameters.
Interpreting Results of Robust Tuning
When you tune a control system with parameter uncertainty, the tuning results contain information about the progress of the tuning algorithm toward tuning for the worst-case parameter values.
