Abstract. Synthesis of linear-quadratic-Gaussian (LQG) controller used in automatic system control of telescope axis precision tracking electric drive is considered. Application of LQG-controller is shown to afford higher accuracy of the system due to robustness to object process noise.
Keywords: robust control, LQG-controller, high precision tracking electric drive.
