- Set Up Your Control System for Tuning with looptune
To uselooptune
, create a parameterized representation of your controller and a numeric model of your plant. - Structure of Control System for Tuning With looptune
looptune
tunes the feedback loop illustrated below to meet default requirements or requirements that you specify. - Tune Control Systems in Simulink
At the command line, usesystune
orlooptune
to automatically tune control systems modeled in Simulink®. - How Tuned Simulink Blocks Are Parameterized
Both Control System Tuner and theslTuner
interface automatically assign predefined parameterizations to certain Simulink blocks. - Mark Signals of Interest for Control System Analysis and Design
Analysis points allow you to access to internal signals, perform open-loop analysis, or specify requirements for controller tuning in systems modeled in either MATLAB® or Simulink. - Using Parallel Computing to Accelerate Tuning
Multiple optimization starts can improve control-system tuning results. If you have Parallel Computing Toolbox™, you can accelerate multi-start tuning strategies.
