Embodiment 1
[0124] A fixed-frequency interference active closed-loop suppression PID wheel control method with a digital structure enhancer provided by an embodiment of the present invention includes:
[0125] Step 1. The rotation speed of the rotating parts on the satellite is unknown, and the angular velocity fluctuation frequency f (Hz) of the satellite is obtained through on-orbit measurement. Then the fixed frequency ωrad / s of the disturbance torque introduced by the rotating parts is:
[0126] ω=2πf.
[0127] Step 2. Design a digital structure enhancer for this frequency, and its transmission schematic diagram is as follows figure 1 As shown, the corresponding expression is:
[0128]
[0129]
[0130]
[0131] The fixed-frequency disturbance torque has components in the X, Y, and Z axes of the satellite, so the expressions of the parameters of the digital structure enhancer are:
[0132]
[0133]
[0134]
[0135]
[0136]
[0137] In the above formula, T i...
