Iterative Learning Control for a class of spatially interconnected systems

摘要

An unconditionally stable finite difference discretization motivated by the well-known Crank-Nicolson method is used to develop an Iterative Learning Control (ILC) design for systems whose dynamics are described by a fourth-order partial differential equation. In particular, a discrete in time and space model of a deformable rectangular mirror, as an exemplar application, is derived and used in the ILC design. Finally, the feasibility of the new ILC design is confirmed by numerical simulations.
