Tuning, Analysis, and Validation

Tune control system parameters and analyze results at the command line

Once your model is set up for tuning, the systune command adjusts the tunable coefficients to meet your design requirements.

Functions

`systune`	Tune control system parameters in Simulink using `slTuner` interface
`systuneOptions`	Set options for `systune`

`getIOTransfer`	Transfer function for specified I/O set using `slLinearizer` or `slTuner` interface
`getLoopTransfer`	Open-loop transfer function at specified point using `slLinearizer` or `slTuner` interface
`getSensitivity`	Sensitivity function at specified point using `slLinearizer` or `slTuner` interface
`getCompSensitivity`	Complementary sensitivity function at specified point using `slLinearizer` or `slTuner` interface
`writeBlockValue`	Update block values in Simulink model
`getTunedValue`	Get current value of tuned variable in `slTuner` interface
`setTunedValue`	Set current value of tuned variable in `slTuner` interface

`viewGoal`	View tuning goals; validate design against tuning goals
`evalGoal`	Evaluate tuning goals for tuned control system

Interpret Numeric Tuning Results
Tuning reports from systune and Control System Tuner give you an overview of how well the tuned control system meets your tuning goals.
Visualize Tuning Goals
Tuning-goal plots let you visualize your design requirements against tuned system responses, to see where and by how much tuning goals are satisfied or violated.
Validate Tuned Control System
When you tune a control system, validate the results by examining system responses with the tuned parameters.
Validating Results
This example shows how to interpret and validate tuning results from systune.

Tune Control System at the Command Line
After building a tunable control system model and specifying tuning goals, use systune to tune the parameters of your system.
Tuning Multiloop Control Systems
Jointly tune the inner and outer loops of a cascade architecture with systune.
Speed Up Tuning with Parallel Computing Toolbox Software
If you have the Parallel Computing Toolbox™ software installed, you can speed up the tuning of fixed-structure control systems.

Control of an Inverted Pendulum on a Cart
This example uses systune to control an inverted pendulum on a cart.
Control of a Linear Electric Actuator
use slTuner and systune to tune the current and velocity loops in a linear electric actuator with saturation limits.
Tune Field-Oriented Controllers Using SYSTUNE
Tune a field-oriented controller for an asynchronous machine in one simulation.

Digital Control of Power Stage Voltage
Tune a high-performance digital controller with bandwidth close to the sampling frequency.
MIMO Control of Diesel Engine
Use systune to design and tune a MIMO controller for a Diesel engine. The controller is tuned in discrete time for a single operating condition.

Multiloop Control of a Helicopter
Use slTuner and systune to tune a multi-loop controller for a rotorcraft.
Fixed-Structure Autopilot for a Passenger Jet
Use slTuner and systune to tune the standard configuration of a longitudinal autopilot.
Fault-Tolerant Control of a Passenger Jet
Achieve reliable control of a passenger jet by tuning a controller for multiple operating modes of the plant.
