  • Publication number: 20240256868
    Abstract: A machine learning (ML) controller and method for systems that can learn to stabilize them based on measurements of an unstable system. This allows for training on a system not yet controlled and for continuous learning as the stabilizer operates. The controller has improved performance on unstable systems compared to similar technologies, especially complex ones with many inputs and outputs. Furthermore, there is no need for modelling the physics, and the controller can adapt to un-analyzed or partially analyzed systems.
