Iterative learning control applied to a deformable mirror

Iterative learning control applied to a deformable mirror
Iterative learning control applied to a deformable mirror
Abstract:
An unconditionally stable finite difference discretization motivated by the well-known Crank-Nicolson method is used to develop an iterative learning control design for systems whose dynamics are described by a fourth-order partial differential equation. A discrete in time and space model of a deformable rectangular mirror is derived in this setting and forms the basis for the new design, where a model for the actuator dynamics is also included. A numerical case study is given to demonstrate the properties of the new design.
