trano-optimization

Optimal control, moving horizon estimation and simulation of Modelica models: rumoca translates the model into a CasADi function, solved by direct collocation with IPOPT.

It works on the Modelica text of an explicit ODE (for instance the building_mpc model that trano generates with the FastSmoothBuildingsMPC library) and does not depend on trano.

from trano_optimization import CasadiModel, OptimalControl

model = CasadiModel.from_modelica(source, "house.building_mpc")
result = OptimalControl(model).solve(initial_state, disturbances, comfort_lower, price)

A model that uses a Modelica library without holding it gives rumoca the folder of the library:

import fastsmoothbuildings

model = CasadiModel.from_modelica(source, "house.building_mpc", roots=[fastsmoothbuildings.LIBRARY])

Installation

pip install trano-optimization

This installs rumoca 0.10.2 from PyPI, which translates flat models. The models of the FastSmoothBuildings libraries are made of connected components, which rumoca exports to CasADi from 0.10.3 only, not released yet: install it from its main branch (Rust toolchain), as [tool.uv.sources] of pyproject.toml does.

pip install "rumoca @ git+https://github.com/CogniPilot/rumoca@33c21141791cbc341f4788ff6353d2f49d1c740a#subdirectory=crates/rumoca-bind-python"
