I can create model via simulink and I can place simulink and simscape component onto the model. I can access to both simscape and simulink components and set their parameters manually.

But, I can set parameter only using m-file only to simulink component. When using m-file to set parameter of simscape component, the parameter is not found.

%% Clear Workspace & Initialize

clear; clc; close all;

%% Load Simscape Library (if not loaded)

if ~bdIsLoaded('simscape')

disp('Loading Simscape library...');

load_system('simscape');

end

%% Create & Open Simulink Model

model_name = 'DAB_Converter_Model';

if bdIsLoaded(model_name)

close_system(model_name, 0);

end

new_system(model_name);

open_system(model_name);

%% Component Integration

%%dc_source_block = 'simelectronics/Sources/DC Voltage Source'; << incorrect source address

dc_source_block = 'fl_lib/Electrical/Electrical Sources/DC Voltage Source';

add_block(dc_source_block, [model_name '/Input_Voltage'], 'Position', [50, 50, 100, 100]);

set_param(model_name'/Input_Voltage', 'Constant Voltage', 100);

Error: Unrecognized function or variable 'Input_Voltage'.

On the model, DC Voltage Source component and the name Input_Voltage are placed. But, it seems Input_Voltage name is not visible to Simulink. How can I make all simscape component visible to simulink via m-file. I can access to the simscape component manually without problem,but not via m-file.

set_param([model_name '/Input_Voltage'], 'v0', '100'); fix this problem.

I was looking at the parameter name of the component which is 'Constant Voltage', but the parameter name can be found by clicking on the component and look at the parameter field. In this case, the Constant Voltage parameter name for the Input_Voltage component is v0.
