摘　　要：针对航天器的姿态控制,提出了一种电磁阀开关量预测控制方法。根据预测控制时间和喷管布局设计电磁阀的点火逻辑,利用喷管的作用力相互抵消,使得控制力矩作用时间可在控制周期内任意调节。通过仿真分析表明,和常规的脉宽调制技术相比,预测控制方法使得电磁阀不受限于最小持续开启时间,能够实现姿态的精确控制。A predictive control method for electromagnetic switching valve is proposed for attitude con⁃trol of spacecraft.Based on the predicted control time and nozzle layout,the ignition logic of electromag⁃netic valve is designed and the force of the nozzle is utilized to cancel out each other,so that the control torque action time can be adjusted arbitrarily during the control cycle.The simulation analysis shows that compared with conventional pulse width modulation techniques,the predictive control method allows the solenoid valve to achieve precise attitude control without being limited to the minimum continuous open⁃ing time.
