摘要	The long transmission distance of satellite ground quantum communication and the relative mo tion between the satellite and ground increase the tracking performance requirements of a quantum tracker. To improve the tracking accuracy of satellite ground quantum communication and reduce the error rate of quantum communicationthe tracking and pointing control system of a quantum tracker is investigated in this studyand the total disturbance affecting the tracking accuracy is compensated. Firstthe satellite ground quantum communication link and the quantum communication process and its influencing factors are introduced. A mathematical model of the quantum tracker is then constructed. Based on the mathemat ical model of the trackeran active disturbance rejection controlADRCmodel predictive control algo rithm is designed and proposed. To solve the problem of mode switchinga fractional order tracking differ entiator is proposed to optimize the trajectory and thus reduce overshoot. Experimental results of quantum communication with the"Mozi"satellite reveal that the fractional order tracking differentiator improves the target acquisition speed by 22% following mode switching. Compared with the traditional PI controlthe proposed ADRC model predictive control has stronger anti-interference capabilitiesweakens the miss dis tance peak of pitch reversaland has a tracking accuracy that reaches 2. 9". The quantum polarization data reception is improvedand the total bit error rate is reduced to 1. 18%. The proposed control algorithm can further improve the tracking accuracy of the quantum trackerreduce the bit error rateand meet the accuracy requirements of satellite ground quantum communication. 2022 Chinese Academy of Sciences.
