mpc_python

I keep here my (old) notebooks on Model Predictive Control for path-following problems. Includes a Pybullet simulation to demo the controller. This mainly uses CVXPY as a framework. This repo contains code from other projecs, check them out in the special thanks section.

Contents

Usage

  • To run the pybullet demo:
python3 mpc_demo_pybullet.py
  • To run the simulation-less demo (simpler demo that does not use pybullet, useful for debugging):
python3 mpc_demo_pybullet.py

In both cases the script will promt the user for enter before starting the demo.

The settings for tuning the MPC controller are in the mpc_config class.

Jupyter Notebooks

  1. State space model derivation -> analytical and numerical derivaion of the model

  2. MPC -> implementation and testing of various tweaks/improvements

  3. Obstacle Avoidance -> Using halfplane constrains to avaoid track collisions -> Sill work in progress!

Results

Racing car model is from: https://github.com/erwincoumans/pybullet_robots.

Requirements

The environment can be repoduced via conda:

conda env create -f env.yml
conda activate simulation

The dependencies for just the python scripts can also be installed using pip:

pip3 install --user --requirement requirements.txt
