MATLAB: Creating a mask/dialog of a subsystem and setting sample time for all components within

dialogmasksample_timesimulink

I have a subsystem that contains a discrete filter block(with various inputs), how can I make my mask/dialog for my subsystem that will set the sample time for the discrete filter within the block?

Best Answer

You can create a mask variable (for example, Ts ) that users can enter in the dialog box.

Then, inside the masked subsystem, you can set the sample time of the filter block to that variable Ts.

You can see how this all looks if you drag in a Discrete PID Controller block, for instance, right-click it, and select Mask > Look Under Mask.

Use the following command to get the list of mask parameters of a block:

get_param('model/sub_block', 'DialogParameters')

To get the values of the masked parameters, you may write as folllows:

dialogPrms = get_param('model/sub_block', 'DialogParameters'); 
dialogPrmNames = fieldnames(dialogPrms); % Parameter names 
for idx = 1:numel(dialogPrmNames) 
   dialogPrmValue = get_param('model/sub_block', dialogPrmNames{idx}) % Parameter values 
end

Parameters of blocks located inside the masked subsystem can be modified from the Mask dialog box by having it 'promoted' to the mask. Please refer to the link for further information on promoted mask parameters:
