Evaluate performance / usability of Stable Baseline RL Package + OpenAI Spinning up

[wallscheid]

Transfer DDPG-based PMSM current control example based on Keras-RL2 to the standard RL packages

• https://github.com/openai/spinningup
• https://github.com/hill-a/stable-baselines

Hence, we require a standard agent able to work on cont. actions and cont. states.

Add-on:

• Set up an educational Jupyter Notebook to showcase the usage of GEM in combination with exemplary RL algorithms from above toolboxes.
• The content of the notebook should be also suitable for beginners to motor control / reinforcement learning.
• The notebook may serve as basis for a tutorial-style video.
