Abstract

The invention discloses a resonant frequency control method, device and system of a quantum communication tracker and a medium, and the method comprises the steps: determining a speed error signal and a target amplitude of resonant frequency when a tracking instruction is detected, and determining a fractional order differential operator according to the target amplitude of the resonant frequency; and inputting the fractional order differential operator into a resonance controller of the quantum communication tracker to generate a first control signal, and adjusting a current amplitude of a resonant frequency to a target amplitude of the resonant frequency based on the first control signal and the speed error signal. According to the invention, a fractional order differential operator is determined according to the target amplitude of the resonant frequency, and the fractional order differential operator is input into the resonant controller of the quantum communication tracker to control the resonant frequency, so that the amplitude of the resonant frequency of the quantum communication tracker is suppressed, and the tracking precision and the communication efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of satellite-to-earth communication, in particular to a method, device, system and medium for controlling the resonant frequency of a quantum communication tracker. Background technique [0002] The quantum communication tracker is a ground device used for quantum communication between the satellite and the earth. At present, the weight of the quantum communication tracker has been greatly reduced through the selection of mechanical materials and the design of a lightweight structure, which is more conducive to portability and contributes to the tracker's Satellite-to-earth quantum communication operations are carried out in multiple locations, but this lightweight design is at the cost of reducing the stiffness between structures, resulting in an excessively large amplitude of the resonant frequency of the quantum communication tracker, which limits the bandwidth of the quantum communication tracker, resulti...
