Model-free LQG Control with Chance Constraints
arXiv:2605.31310v1 Announce Type: new Abstract: This paper studies model-free optimal control design and its convergence properties for linear time-invariant systems subject to probabilistic risk or chance constraints. In particular, we study a natural policy gradient (NPG)-based actor-critic (AC) algorithm with two timescales, using a Lagrangian primal-dual framework to enforce the constraint.
Comparing sliding-mode, bang-bang and linear-quadratic-Gaussian for steering an atomic clock
arXiv:2605.20156v2 Announce Type: replace Abstract: Accurate timekeeping relies on feedback that continually steers a local clock toward a higher-grade reference. We evaluate first-order sliding-mode control (SMC) for steering an atomic clock and benchmark it against two standards: linear-quadratic-Gaussian (LQG) control and the bang-bang (BB). All three are tested in a common numerical framework using the standard two-state clock model driven by white and random-walk-frequency noise.
