Abstract: Adaptive optics systems represent a significant challenge for the controller design. The output disturbance must be compensated despite a significant measurement noise and timedelays. This paper presents the formulation of a discrete Linear Quadratic Gaussian controller, which includes a realistic model of the measurement noise. The correspondence between the photosensor noise in the sensor and the measurement noise is established. Different cases of the system’s operation are considered. The influence of the measurement noise on the discrete LQG controller in adaptive optics systems is discussed.
Keywords: optimal control, adaptive optics, measurement noise, numerical simulations.
