Hi Yeow,
I am assuming you want to assign values to constant blocks u1 and u2 from Python and extract values of x1 and x2 after some simulation on your model.
In order to achieve the workflow mentioned by you there are roughly 3 steps can follow:
- Set values to the constant blocks u1 and u2 from Python.
- Run the Simulink model.
- Retrieve the outputs x1 and x2 from the MATLAB workspace back to Python.
Start the MATLAB engine
eng = matlab.engine.start_matlab()
Load the Simulink model
eng.load_system(model_name, nargout=0)
Set values to the constant blocks u1 and u2
eng.set_param(f'{model_name}/u1', 'Value', str(u1), nargout=0)
eng.set_param(f'{model_name}/u2', 'Value', str(u2), nargout=0)
Run the Simulink model
eng.set_param(model_name,SimulationCommand="start")
Wait for the simulation to finish
eng.set_param(model_name,SimulationCommand="stop")
Retrieve the outputs x1 and x2
x1 = eng.eval('out.x1', nargout=1)
x1_data =x1.Data
x2 = eng.eval('out.x2', nargout=1)
x2_data =x2.Data
The above steps/code might not be exactly according to your coding structure but is a rough idea/implementation on how you can achieve the desired workflow.
I hope it helps you to get started!
