Simulink Control Design™ - MathWorks

Example: blk = 'scdcascade/C1', blk = "C1"

NotesetBlockValue allows you to modify only the overall value of the

parameterization of blk. To modify the values of elements within custom block

parameterizations, such as generalized state-space models, use setTunedValue.

value — Value of block parameterization

numeric LTI model | control design block

Value of block parameterization, specified as a numeric LTI model (Control System

Toolbox) or a Control Design Block (Control System Toolbox), such tunableGain or

tunablePID. The value of value must be compatible with the parameterization of blk.

For example, if blk is parameterized as a PID controller, then value must be an

tunablePID block, a numeric pid model, or a numeric tf model that represents a PID

controller.

setBlockValue updates the value of the parameters of the tuned block based on the

parameters of value. Using setBlockValue does not change the structure of the

parameterization of the tuned block. To change the parameterization of blk, use

setBlockParam. For example, you can use setBlockParam to change a block

parameterization from tunablePID to a three-pole tunableTF model.

blkValues — Values of multiple block parameterizations

structure

Values of multiple block parameterizations, specified as a structure with fields specified

as numeric LTI models or Control Design Blocks. The field names are the names of blocks

in st. Only blocks common to st and blkValues are updated, while all other blocks in

st remain unchanged.

To specify blkValues, you can retrieve and modify the block parameterization value

structure from st.

blkValues = getblockValue(st);

blkValues.C1 = pid(0.1,0.2);

NoteFor Simulink blocks whose names are not valid field names, specify the

corresponding field name in blkValues as it appears in the block parameterization.
