[0092] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0093] like figure 1 As shown in the present invention, a flexible satellite pointing and tracking control method including a six-degree-of-freedom vibration isolation platform, the specific implementation steps are as follows:
[0094] Step 1: According to figure 2 The system shown in Figure 1 establishes the dynamic model of the upper and lower platforms of the flexible satellite with a six-degree-of-freedom vibration isolation platform.
[0095] Ignoring the external disturbance to the upper platform system, considering the static and dynamic imbalance of the rotor of the control moment gyroscope, the non-perpendicular and non-intersecting frame axis and the rotor axis, the dynamic equation of the vibration isolation upper platform system is as follows:
