​Congratulation to W. Cai et al for their paper accepted in the 2nd IEEE Conference on Control Technology and Applications​ which will be hold in Copenhagen, Denmark, August 21-24, 2018. ​​​​​​​
In this paper authors propose a robust H-infinity approach for free space optical (FSO) beam pointing error systems. First, a deterministic discrete-time model for pointing error loss due to misalignment  is presented. This model  considers detector aperture size and optical beam width. Then, the control problem that guarantees the stability of the closed-loop pointing error and the attenuation of the  disturbance is investigated through a robust H-infinity  control framework. Finally, simulation results of the FSO link under the effects of a controlled weak turbulence condition are performed to demonstrate the feasibility of the proposed robust pointing error approach.
