How to import a transfer function from workspace into simulink?
显示 更早的评论
I have a MATLAB script that creates two transfer functions and I want to use them in simulink. I could use a transfer function block and enter the function by hand, but I'm using numerous functions on numerous sets of data. I want to import the functions and automate the process as much as possible. Any help would be greatly appreciated.

I actually have the same problem, and I checked the input arguments from the set_param documentation: set_param
I also checked the Parameters for the type Discrete Transfer Fcn (DiscreteTransferFcn) on this page Block-Specific Parameters
However, if I try to compile this code:
ProbSet3_Ex1c
set_param('ProbSet3_Ex1c/D','Denominator',[1 0 0],
'Numerator',[2 3 5],'SampleTime',1);
I always get this error:
Invalid setting in DiscreteTransferFcn block 'D' for parameter 'Denominator'
The same error appears, if I just try to change the SampleTime:
ProbSet3_Ex1c
set_param('ProbSet3_Ex1c/D','SampleTime',1);
Any ideas? Thanks a lot for helping!

Try
ProbSet3_Ex1c
set_param('ProbSet3_Ex1c/D','Denominator',mat2str([1 0 0]),
'Numerator',mat2str([2 3 5]),'SampleTime',1);

Use
get_param('your_model_name/your_block_name','DialogParameters')

Hi guys, I have the same problem when I want to use the "from workspace" block in simulink to bring data to simulink, actually I wanted to bring a transfer function from workspace to simulink, not a data, and I see that this block just have output port in, not any input , so I can not connect this block from input to another block. How can I do that?
Thank you
Rik

@azam, instead of reposting your comment as a flag, have a read here and here. It will greatly improve your chances of getting an answer.
As far as I understand it, 'from workspace' can only load things from the base workspace. That means you can only use it to load data. Functions are not inside a workspace.
