This contribution introduces a novel, adaptive method to compensate for constant time-delays in potentially highly nonlinear, spatially distributed mixed real-virtual prototypes, using small feedforward neural networks.

Because of the vanishing gradient at a local minimum, the NeuralODE is often not capable of leaving it and converge to the right solution.

The term NeuralODE describes the structural combination of an Artifical Neural Network (ANN) and a numerical solver for Ordinary Differential Equations (ODEs), the former acts as the right-hand side of the ODE to be solved.

We propose a non-adversarial learning-from-observations approach, together with an interpretable convergence and performance metric.

Our training objective minimizes the Kulback-Leibler divergence between the policy and expert state transition trajectories which can be optimized in a non-adversarial fashion.

This paper covers two major subjects: First, the presentation of a new open-source library called FMI. jl for integrating FMI into the Julia programming environment by providing the possibility to load, parameterize and simulate FMUs.
