| 摘 要： | 采用非接触洛伦兹力执行器代替微推进系统，提出一种“质量块—载荷舱—平台舱”三体随动跟踪式重力卫星总体架构，避免传统低低跟踪重力场测量卫星设计中的质心波动与执行机构带来的动力学不确定性影响。其次，建立了该架构下的卫星姿轨耦合动力学模型，并在此基础上针对动力学非线性耦合项的影响，构建了一种基于带宽参数化自适应补偿的复合自抗扰控制方法，提升姿态与无拖曳控制性能。最后，采用数学仿真验证了所提出的重力卫星总体架构及其控制方法的有效性。仿真结果表明，该方法有效提升了系统的频域性能。

| Abstract: | A non contact Lorentz actuator is used to replace the micropropulsion system, and a three body close tracking satellite architecture of “proof mass payload module service module” is proposed to avoid the influence of the dynamics uncertainty caused by the centroid fluctuation and the actuator in the design of traditional low low gravity tracking field measurement satellite. Secondly, the coupling attitude control and orbital control dynamics under this architecture is established, and a composite active disturbance rejection control based on bandwidth parameterization is constructed to deal with the nonlinear coupling dynamics, and to improve the attitude and drag free control performance. Finally, the extensive numerical simulation is conducted to validate the effectiveness of the proposed approach. The simulation results show that the proposed approach can be used to improve the systematic performance in the frequency domain. |
