摘要
基于STK仿真软件研究了多卫星寻迹编队控制问题.利用滑模控制方法设计单颗卫星轨迹跟踪控制律用以对抗引力摄动,同时在STK仿真环境中验证了该算法的有效性.为了在STK中实现基于双向通信的卫星寻迹编队任务,利用C++语言设计了一个分时有序调用插件解决了STK仿真中的计算独占的问题和仿真计算中心不返回当前卫星标识符的问题.在此基础上,利用STK仿真验证了解耦法设计的寻迹编队算法的有效性,STK仿真结果比Matlab仿真结果更有实用意义.
The problem of satellite formation tracking control is studied by using the tool, the satellite tool kit （STK ） software.To fight against gravitational perturbation rejection, a sliding mode controller for each satellite is proposed to accomplish the orbit trace and is then verified by the STK.For the purpose of accomplishing the formation tracking mission with bidirectional communication in STK,a time-share orderly calling plug-in is designed by C ＋＋,which gives solutions to the problems of the monopolization of computing resource and no return of the satellite identifier in the calculation center. The effectiveness of the decoupling approach is tested and verified by the STK.The simulation results obtained by the STK are more meaningful than those obtained by Matlab.
