PRESCRIBED-TIME STABILIZATION- NOISE-ROBUSTNESS, GENERALIZATIONS, APPLICATIONS
Abstract
This proposal is inspired by the ability of an archaic, 1950’s-era (pre-modern control), missile guidance law, commonly referred to as ‘proportional navigation’ (PN), to achieve regulation (i.e., to strike a target) faster than exponentially, and not only within some finite time that the user can’t arbitrarily set, but within a user-prescribed finite time. (To make the proposal self-contained, we provide some detail on PN and missile guidance in Appendix A.) Until recently, such capability of prescribed-time regulation has been exclusive to the heuristic setting of PN. Discontinuous control laws, such as sliding mode controls, only achieve finite-time regulation, with the convergence time dependent on the initial conditions (the larger the initial condition, the longer the convergence time, typically).
