Clone/ Copy a subsystem reference with new set of indexed parameters

1 view (last 30 days)
Hi,
I have a large simulink model with multiple instances of a subsytem referenced blocks. Each subsytem referenec has four parameters which are indexed as shown in pictures.
For exampe for block name "E7kW_Long Range27" the parmeters are Chrg_Start_E7L(27), Batt_cap_E7L(27) etc. ie the last two digits of the block name (27) is the index of array defined in worksapce.
Is there any way that I can create a copy/ clone this block with the parameter index automatically updated. ie the copy is created as "E7kW_Long Range28" and parameters as Chrg_Start_E7L(28), Batt_cap_E7L(28) etc. with index updated to 28.
Thanks

I understand that you want to automatically clones a subsystem and updates the parameters based on the block name in Simulink. You can create a MATLAB script to automate this process. The script would copy the subsystem, rename it, and update the parameter settings accordingly. Here is the conceptual code for that:
% Define the base block name and the current index
baseBlockName = 'E7kW_Long Range';
currentIndex = 27;
newIndex = currentIndex + 1;
% Define the subsystem's parent path
parentSystem = 'your_model_name/SubsystemParentPath';
% Define the original and new block paths
originalBlockPath = [parentSystem '/' baseBlockName num2str(currentIndex)];
newBlockPath = [parentSystem '/' baseBlockName num2str(newIndex)];
% Copy the subsystem block to the new location with the new name
add_block(originalBlockPath, newBlockPath);
% Define the parameter names
paramNames = {'Chrg_Start_', 'Batt_cap_', 'ThirdParam_', 'FourthParam_'};
% Update the parameters in the new subsystem
for i = 1:length(paramNames)
% Construct the original and new parameter names
originalParamName = [paramNames{i} 'E7L(' num2str(currentIndex) ')'];
newParamName = [paramNames{i} 'E7L(' num2str(newIndex) ')'];
% Get the original parameter value using get_param
originalValue = get_param(originalBlockPath, 'MaskValues');
% Replace the original parameter name with the new one
newValue = strrep(originalValue, originalParamName, newParamName);
% Set the new parameter value using set_param
set_param(newBlockPath, 'MaskValues', newValue);
end
% Now the new subsystem block has been created and the parameters updated
You may have to update few values in order to suit your requirement.
Thanks,

Thanks a lot @Ayush.... It worked perfectly.
Just a little change to make it work as below.
% Define the base block name and the current index
for k=1:10
baseBlockName = 'E7kW_Long Range';
currentIndex = k;
newIndex = currentIndex + 1;
% Define the subsystem's parent path
parentSystem = 'UrbanGenericLV24hrADMD_7kW';
% Define the original and new block paths
originalBlockPath = [parentSystem '/' baseBlockName num2str(currentIndex)];
newBlockPath = [parentSystem '/' baseBlockName num2str(newIndex)];
% Copy the subsystem block to the new location with the new name
add_block(originalBlockPath, newBlockPath);
% Define the parameter names
paramNames = {'Chrg_Start_', 'Eff_','Batt_cap_','SoC_init_'};
% Update the parameters in the new subsystem
for i = 1:length(paramNames)
% Construct the original and new parameter names
originalParamName = [paramNames{i} 'E7L(' num2str(currentIndex) ')'];
newParamName = [paramNames{i} 'E7L(' num2str(newIndex) ')'];
% Get the original parameter value using get_param
originalValue = get_param(originalBlockPath, 'MaskValues');
% Replace the original parameter name with the new one
% newValue = strrep(originalValue, originalParamName, newParamName);
newValue{i} = newParamName
end
% Set the new parameter value using set_param
set_param(newBlockPath, 'MaskValues', newValue);
end
% Now the new subsystem block has been created and the parameters updated
