Embodiment
[0095] This embodiment example process figure 1 As shown, the attitude control of the networked spacecraft system based on the hybrid forced observer is realized through the following steps:
[0096] Step 1: Construct a networked spacecraft attitude dynamics model with spoofing attacks
[0097] The expression of spacecraft attitude dynamics is:
[0098]
[0099] in,
[0100] M(q(t))=Z -T (q(t))JZ -1 (q(t));τ(t)=Z -T (q(t))u(t); d 0 (t)=Z -T (q(t))d τ (t);
[0101]
[0102]
[0103] is the modified Rodrigue parameter vector, which is used to represent the attitude of the spacecraft;
[0104] is the positive definite symmetric inertia matrix of the spacecraft, is the control torque of the spacecraft, is the external disturbance moment of the spacecraft, S(·) represents a skew symmetric matrix function, for example:
[0105]
[0106] And choose J=diag{4,5,4}(kgm 2 ),
[0107] let x 1 (t)=q(t), Considering the spacecraft attitude information me...
