Coupling-moment analysis and its feed forward technique of three axes antenna

In this paper,based on the analyse of the working theory of three axes antenna and the diagnostics of coupling torque produced by AZ and the 3rd axis.A feedforward compensation method is proposed to reduce the affection of the coupling disturbance on system tracking.Simulink is used to simulate and modeling in feedforward compensation design,The result proves the method is effective to eliminate the coupling disturbance of three axes antenna.
