wcg — Worst constraint value

positive scalar

Largest hard goal value over the uncertainty range when using the tuned controller.

(Applies for robust tuning of control systems with uncertainty only.)

wcDecay — Worst decay rate

scalar

Smallest closed-loop decay rate over the uncertainty range when using the tuned

controller. (Applies for robust tuning of control systems with uncertainty only.) A positive

value indicates robust stability. See MinDecay option in systuneOptions for details.

Tuned Blocks

Tuned blocks, used by the slTuner interface, identify blocks in a Simulink model whose

parameters are to be tuned to satisfy tuning goals. You can tune most Simulink blocks

that represent linear elements such as gains, transfer functions, or state-space models.

(For the complete list of blocks that support tuning, see “How Tuned Simulink Blocks Are

Parameterized” on page 10-36). You can also tune more complex blocks such as

SubSystem or S-Function blocks by specifying an equivalent tunable linear model

(Control System Toolbox).

Use tuning commands such as systune to tune the parameters of tuned blocks.

You must specify tuned blocks (for example, C1 and C2) when you create an slTuner

interface.

st = slTuner('scdcascade',{'C1','C2'})

You can modify the list of tuned blocks using addBlock and removeBlock.

To interact with the tuned blocks use:

• getBlockParam, getBlockValue, and getTunedValue to access the tuned block
  parameterizations and their current values.


• setBlockParam, setBlockValue, and setTunedValue to modify the tuned block
  parameterizations and their values.
