Adaptive control problem solved: Exact value for adversarial scenarios determined

By PulseAugur Editorial · [1 sources] ·

Researchers have solved a fundamental problem in adaptive control theory, determining the exact value of scalar adversarial adaptive control under significant parametric uncertainty. The study establishes that the least worst-case peak value a causal controller can guarantee against adversarial disturbances is precisely 1 + \u0394, where \u0394 represents the arbitrary size of the parametric uncertainty. The optimal policy identified is a certainty-equivalent deadbeat control strategy, which operates at the midpoint of the set-membership consistent interval. This approach provides the first exact optimality certificate for the 'consistent model chasing' design principle in adversarial adaptive control, demonstrating that standard control tools are quantifiably insufficient.

    Consistent Model Chasing Is Minimax Optimal: The Exact Value of Scalar Adversarial Adaptive Control under Large Parametric Uncertainty

    arXiv:2608.13651v1 Announce Type: cross Abstract: We solve exactly a fundamental problem of adaptive control against adversarial disturbances: regulate the scalar system $x_{t+1} = ax_t + u_t + w_t$, $x_0=0$, $\|w\|_\infty \le 1$, where the constant pole $a \in [-\Delta, \Delta]$…
