System identification

A (basic) implementation for the identification of non-linear systems implemented using the machine learning library JAX (https://github.com/google/jax). Herein, automatic differentiation of the system model and the through the ODE solver is used to enable gradient-based optimization approaches.

An example notebook describing the identification for a pendulum is provided https://nbviewer.org/github/christianausb/controlAlgorithms/blob/main/examples/sysident.ipynb

State trajectory estimation and system identification

A routine for estimating the state trajectory and system parameters from input/output data and a prototype model is provided. The following example demonstrates the use for a pendulum system:

Pendulum motion estimation from video recordings

This experiment demonstrates how to combine state and parameter estimation with a deep neural autoencoder to estimate motion trajectories from video-recordings.
