Simulink Control Design™ - MathWorks

Interface for tuning control systems modeled in Simulink, specified as an slTuner

interface.

blk — Block

character vector | string | cell array of character vectors | string array | positive integer |

vector of positive integers

Block to remove from the list of tuned blocks on page 15-442 for st, specified as one of

the following:

• Character vector or string — Full block path or any portion of the block path that
  uniquely identifies the block among the other tuned blocks of st. For example, blk =
  'scdcascade/C1'.


• Cell array of character vectors or string array — Specifies multiple blocks. For
  example, blk = {'C1','C2'}.


• Positive integer — Block index. For example, blk = 1.


• Vector of positive integers — Specifies multiple block indices. For example, blk = [1
  2].

To determine the name or index associated with a tuned block, type st. The software

displays the contents of st in the MATLAB command window, including the tuned block

names.

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.
