Grundlagen von Loop-Shaping
- 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
looptunetunes the feedback loop illustrated below to meet default requirements or requirements that you specify. - Tune MIMO Control System for Specified Bandwidth
Tune a fixed-structure MIMO control system to achieve a specified loop crossover frequency usinglooptune. - Tune Feedback Loops Using looptune
Thelooptunecommand facilitates loop shaping design by automatically generating the tuning requirements. - How Tuned Simulink Blocks Are Parameterized
Both Control System Tuner and theslTunerinterface automatically assign predefined parameterizations to certain Simulink® blocks. - Tune Control Systems in Simulink
At the command line, usesystuneorlooptuneto automatically tune control systems modeled in Simulink. - Building Tunable Models
Build a control-system model for tuning withsystuneorlooptuneusing numeric LTI models for fixed elements and control design blocks for the tunable elements. - 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.
