Model Reference Adaptive Control with Linear-like Closed-loop Behavior Open
It is typically proven in adaptive control that asymptotic stabilization and tracking holds, and that at best a bounded-noise bounded-state property is proven. Recently, it has been shown in both the pole-placement control and the $d$-step…

A Convolution Bound Implies Tolerance to Time-variations and Unmodelled\n Dynamics Open
Recently it has been shown, in several settings, how to carry out adaptive\ncontrol for an LTI plant so that a convolution bound holds on the closed-loop\nbehavior; this, in turn, has been leveraged to prove robustness of the\nclosed-loop …

Classical d-Step-Ahead Adaptive Control Revisited: Linear-Like Convolution Bounds and Exponential Stability (Extended Version) Open
Classical discrete-time adaptive controllers provide asymptotic stabilization and tracking; neither exponential stabilization nor a bounded noise gain is typically proven. In recent work it has been shown, in both the pole placement stabil…

Exponential Stability for Adaptive Control of a Class of First-Order Nonlinear Systems Open
In adaptive control it is typically proven that a weak asymptotic form of stability holds; furthermore, at best it is proven that a bounded noise yields a bounded state. Recently, however, it has been proven in a variety of scenarios that …

Mg ii Absorption at 2 Open
We present statistics from a survey of intervening Mg ii absorption toward 100 quasars with emission redshifts between z = 3.55 and z = 7.09. Using infrared spectra from Magellan/FIRE, we detect 280 cosmological Mg ii absorbers, and confir…

Classical discrete-time adaptive control revisited: Exponential stabilization Open
Classical discrete-time adaptive controllers provide asymptotic stabilization. While the original adaptive controllers did not handle noise or unmodelled dynamics well, redesigned versions were proven to have some tolerance; however, expon…
