At the command line, use looptune to tune
SISO or MIMO feedback loops using a loop-shaping approach. looptune tunes
a feedback loop to specified bandwidth and stability margins. In Control
System Tuner, use Quick Loop Tuning for loop shaping
of feedback loops.
Set Up Your Control System for Tuning with looptune
To use looptune, 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 MIMO Control System for Specified Bandwidth
Tune a fixed-structure MIMO control system to achieve a specified loop
crossover frequency using looptune.
Tuning Feedback Loops with LOOPTUNE
The looptune command facilitates loop shaping design by
automatically generating the tuning requirements.
How Tuned Simulink Blocks Are Parameterized
Both Control System Tuner and the slTuner interface automatically
assign predefined parameterizations to certain Simulink® blocks.
Tune Control Systems in Simulink
At the command line, use systune or
looptune to automatically tune control systems modeled in
Simulink.
Build a control-system model for tuning with systune or
looptune using 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.
Quick Loop Tuning of Feedback Loops in Control System Tuner
Tune a control system to meet specified bandwidth and stability margins in Control System Tuner, without explicitly creating tuning goals that capture these requirements.
