The invention provides a thrust control method for a microwave ion propulsion system. The thrust control method comprises the steps that a thrust range, a working medium flow range, a pressure adjusting range and a duty ratio adjusting range are preset; a PID control method is applied, PID parameters are determined through ground experiments, and a duty ratio target value and a pressure target value are set; in actual operation, a thrust target value is given, fine adjustment of the pressure and the duty ratio of the electromagnetic valve is carried out through PID, the corresponding target value is achieved, then the thrust precision is improved, the high-precision and high-stability thrust requirements of a microsatellite are met, and the method has wide application prospects in the technical field of space propulsion.

    本发明提供一种微波离子推进系统推力控制方法,预设推力范围、工质流量范围、压力调节范围和占空比调节范围;应用PID控制方法,经由地面实验,确定PID参数,设定占空比目标值和压力目标值;实际运行中,给定推力目标值,使用PID进行压力和电磁阀占空比的精细调节,使其达到对应目标值,进而提高推力精度,满足微小卫星高精度、高稳定性的推力需求,在空间推进技术领域具有广泛的应用前景。
