SoftGoals — Soft goals (objectives)

vector of TuningGoal objects

Soft goals (objectives) for tuning the control system described by st0, specified as a

vector of TuningGoal objects. For a complete list, see “Tuning Goals”.

systune tunes the tunable parameters of the control system to minimize the maximum

value of the soft tuning goals, subject to satisfying the hard tuning goals (if any).

HardGoals — Hard goals (constraints)

vector of TuningGoal objects

Hard goals (constraints) for tuning the control system described by st0, specified as a

vector of TuningGoal objects. For a complete list, see “Tuning Goals”.

A hard goal is satisfied when its value is less than 1. systune tunes the tunable

parameters of the control system to minimize the maximum value of the soft tuning goals,

subject to satisfying all the hard tuning goals.

opt — Tuning algorithm options

options set created using systuneOptions

Tuning algorithm options, specified as an options set created using systuneOptions.

Available options include:

• Number of additional optimizations to run starting from random initial values of the
  free parameters


• Tolerance for terminating the optimization


• Flag for using parallel processing

See the systuneOptions reference page for more details about all available options.

Output Arguments

st — Tuned interface

slTuner interface
