Component synthesis vibration suppression method of two component forces for flexible spacecraft

Considering the characteristics of two component forces on component synthesis vibration suppression(CSVS) method, two theorems on two component forces suppressing fractional multiple design frequency are given respectively. Meanwhile, the control force, which is composed by two arbitrary component forces with different initial time, can suppress certain frequencies for secondorder undamped vibration system. Using the above theorems, control moment of jet attitude maneuver on flexible spacecraft is designed on the basis principle of CSVS method. The simulations validate the correctness and effectiveness of the proposed method.
