cosim fmu import and train

[linyunfeng201203]

Question 1. If I want to import my own model from MATLAB Simulink and export it as kosim type FMU and FMU joint simulation model in openmodelica, can this tool realize simulation training.
Question 2. In this toolbox, why is the modeling of PI controller not carried out in openmodelica? Second, is it implemented through Python code, which increases the complexity of function implementation

Thank you for the question and sorry for the late response.

1.: In general possible to built an FMU with MATLAB Simulink and use it with openmodelica-microgrid-gym (OMG). You only have to check how to get access to the control and measure variables. For example: With

lc1.inductor1.i

you get access to the current flowing through the inductor (in openmodelica named inductor1) as a component of the filter lc1.
In MATLAB you would have to check the naming and format to see how to get access from OMG.

2.: Of course you can run the PI controller in openmodelica as well. The execution in python is with regard to the later application of an reinforcement learning (RL) agent. There the goal was to use standard toolboxes which are typically implemented in python an use the gym interface.
