pymoskito 0.4.0

Python based modular simulation & postprocessing kickass toolbox

PyMoskito

PyMoskito stands for Python based modular simulation & postprocessing kickass toolbox and is Free software (GPLv3)

PyMoskito is targeted at students and researchers working in control engineering. It takes care of all structure related programming a let’s you focus on the important things in life: control design.

It features a modular control loop structure that already contains most of the needed blocks a control engineer needs. Basically you implement your systems dynamics as well as a fancy control law and you are ready to go. On top PyMoskito also contains a GUI which let’s you easily fine-tune the parameters of your simulation.

Go ahead and give it a try!

PyMoskito at work

The main application simulating the Tandem Pendulum system:

Still here? So PyMoskito features

• Quick setup due to lightweight dependencies

• Modular control loop structure allowing easy configuration

• Easy integration of own system models through open interface

• Automatic simulation of simulation regimes (i.e. for parameter ranges)

• Export of simulation results for dedicated post processing

• VTK based 3D visualization interface

• Playback functions for 3D visualization

• Ready-to-go graphs for all simulation signals

• Execution of external C++ code via pybind11

Getting started

Install with pip:

$ pip install pymoskito

and run an example:

$ python -m pymoskito.examples.pendulum
