This open-source software includes simulation models and controllers for electric machine drives and grid converter systems. The machine models include an induction machine, a synchronous reluctance machine, and a permanent-magnet synchronous machine. Various subsystem models are provided for modeling grid converter systems, such as an LCL filter connected to an inductive-resistive grid.
The system models are simulated in the continuous-time domain while the control algorithms run in discrete time. The default solver is the explicit Runge-Kutta method of order 5(4) from scipy.integrate.solve_ivp. Various control algorithms are provided as examples. The documentation is available here:

This software can be installed using pip:
pip install motulatorAlternatively, the repository can be cloned:
https://aalto-electric-drives.github.io/motulator/installation.html
The system models, controllers, reference sequences etc. are easy to configure. As a starting point, example scripts and Jupyter notebooks can be downloaded here:
https://aalto-electric-drives.github.io/motulator/auto_examples/index.html
New system models and controllers can be developed using the existing ones as templates.
If you'd like to help us develop motulator, please have a look at these guidelines first.
