Analysis of Disturbance Torque Caused by Air-bleed for Single Solar Wing
摘要
Abstract
During geostationary orbit satellite sun-oriented stability control process after solar wing deployed in transfer orbit,the influence on attitude of disturbance torque caused by initial air-bleed of solar wing cannot be ignored.In this paper,the disturbance torque is estimated using satellite attitude dynamics model,attitude change and the parameters of the thrusters.The theory imitates really and verified the accuracy of estimating the method.Through related parame-ters in-orbit of FY-4 satellite,the result shows that the air-bleed duration of FY-4's single solar wing lasted nearly 1 1 hours and the initial maximum disturbance torque is 3 7 mN·m,which is about 2 orders of magnitude larger than the solar pressure torque and the influence on attitude cannot be negligible.The estimation result is visual and believable,and can provide the basis for the design of control system on ground and the modification of control parameters in-orbit.关键词
