We propose a probabilistic learning algorithm, based on that of Deisenroth & Rasmussen (2011), to train control policies for nonlinear systems with unknown, or partially unknown, dynamics. In particular, we address the issue of how to incorporate domain-specific knowledge in the form of known, or approximate, relationships between the state variables. This covers the common case of position-velocity relationships but can also be used to tackle reference tracking problems. We demonstrate our approach on some learning problems including the simulated robotic unicycle.
