Paper Abstract

The effects of a controller on the residual wavefront variance in an adaptive optics system can be represented by a discrete-time system. Consequently, the controller design is optimized by the solution of a discrete-time Linear- Quadratic-Gaussian (LQG) problem. This paper analyzes the structure of the LQG controller and the effects of varying loop delay and actuator lag on the controller. The loop delay is represented as a delay of actuator commands to emphasize the structure.
