Paper Abstract

The controller is one of the essential components of a multi-conjugate adaptive optics (MCAO) system. We present in this paper a preliminary comparison in performance based on numerical simulations of two simple control laws for a star-oriented MCAO configuration. The first control law is based on a TSVD reconstruction matrix and a constant-gain integrator, and the second one is based on an optimized modal gain integrator. These control laws will be validated experimentally with the Multi-conjugate Adaptive Optics Demonstrator (MAD).
