摘　　要：针对微波离子推力器工作中出现的非预期电击穿及温漂带来的推力低频扰动,兼顾无拖曳系统超低带宽及强鲁棒需求,将其转换为频域约束指标,并以扰动抑制能力为目标函数设计了分数阶PID作为无拖曳控制器。仿真研究表明,相比较经典的PID控制器,该控制对系统的各种扰动具有良好的鲁棒性,能够抑制推力器打火、温漂带来的控制影响,最终实现了更高的控制精度。研究为考虑微推进系统的引力波探测无拖曳卫星高精度控制方法提供了借鉴。Considering low-frequency disturbance of thrust caused by unexpected electrical breakdown and temperature drift in the operation of microwave ion thruster,as well as the ultra-low bandwidth and strong robustness requirements of the drag-free system,which is converted into a frequency domain constraint index,a fractional-order PID was designed as a drag-free controller with perturbation suppression capability as objective function.Simulation study shows that the control had good robustness to various disturbances of the system compared with the classical PID controller,and could suppress the control effects brought by thruster firing and temperature drift,and finally achieved higher control accuracy.The research provides reference for the high-precision control method of gravitational wave detection without dragging satellite considering micro-propulsion system.
