What the math gives to ML

This paper provides a constructive geometric certificate for whether a constrained actuator can continue stabilizing a system after part of its wrench budget has been consumed by a persistent task. The transferable asset is the feasible-polytope interior margin: instead of checking only rank or unconstrained controllability, a policy can be trained or filtered to keep its requested action away from actuator-feasibility boundaries. The most direct neural-network use is a safety layer for an aerial-control or safe-RL policy that projects task commands into the feasible wrench polytope and penalizes low residual authority, with the margin computed differentiably from a half-space representation or a small allocation linear program.

Residual-authority policy shield

Augment a neural controller with a differentiable residual-authority margin that measures the distance between the requested task wrench and the boundary of the actuator-feasible wrench polytope. During training, penalize commands with small margin; during deployment, project the policy output onto the largest-margin feasible wrench that remains close to the requested output. This should reduce saturation-induced failures during sustained contact and improve robustness to disturbances that…
