System, pose are with subsystem and the working condition of interference excitation analog subsystem, the vibration measurement to analog solar cell array
The three-axis attitude angle and three-axis attitude angular velocity information of information and three axle air floating platforms are filtered analysis, and with desired simulation
The three-axis attitude angle of solar array vibration information and three axle air floating platforms is contrasted with three-axis attitude angular velocity information, from
And the effect of flexible vibration suppressing method and attitude control method is estimated.
10. ground physical emulation verification method as claimed in claim 8, it is characterised in that the verification method is also included：Monitoring
Subsystem monitors analog solar cell array, high accuracy zero-g simulation system, pose are with subsystem and interference excitation simulation
The working condition of subsystem, according to working condition respectively to analog solar cell array, high accuracy zero-g simulation system, pose
Real-time regulation or break-off are carried out with subsystem and interference excitation analog subsystem or be stopped, and detect three axle gas
The real-time three-axis attitude angle of floating platform and three-axis attitude angular velocity information, and it is right with desired attitude angle and attitude angular velocity instruction
Than determining the attitude control accuracy of satellite attitude control system.
