Minimum energy density steering of linear systems with Gromov-Wasserstein terminal cost
CoRR(2024)
摘要
In this study, we address optimal control problems focused on steering the
probabilistic distribution of state variables in linear dynamical systems.
Specifically, we address the problem of controlling the structural properties
of Gaussian state distributions to predefined targets at terminal times. This
task is not yet explored in existing works that primarily aim to exactly match
state distributions. By employing the Gromov-Wasserstein (GW) distance as the
terminal cost, we formulate a problem that seeks to align the structure of the
state density with that of a desired distribution. This approach allows us to
extend the control objectives to capture the distribution's shape. We
demonstrate that this complex problem can be reduced to a Difference of Convex
(DC) programming, which is efficiently solvable through the DC algorithm.
Through numerical experiments, we confirm that the terminal distribution indeed
gets closer to the desired structural properties of the target distribution.
