The invention discloses an attitude and orbit integrated control method based on orbit control thruster pulse width modulation. The method comprises the steps that 1, nozzles of four thrusters are located in the same plane and are parallel to the XOY plane; 2, the thruster starts orbit control; 3, the thruster continues to conduct track control; 4, the track controls the thruster to continuously start signals and measure postures; 5, calculating a deviation attitude; 6, judging whether the X-axis posture and the Y-axis posture are deviated or not: 7, turning off the T2 and sending a signal ifthe X-axis posture is positively deviated, turning off the T4 and sending a signal if the X-axis posture is negatively deviated, turning off the T3 and sending a signal if the Y-axis posture is positively deviated, and turning off the T1 and sending a signal if the Y-axis posture is negatively deviated; step 8, superposing the four signals with a continuous starting signal of a track control thruster, and judging whether the ignition duration is met or not; and 9, if not, the steps 3-8 are repeated, and if yes, track control is ended. The effect of 6-14 rail control thrusters of the same typecan be achieved only through four symmetrically-installed rail control thrusters.

    本发明公开了一种基于轨控推力器脉宽调制的姿轨一体化控制方法。步骤1:4台推力器喷口位于同一平面内且平行于XOY平面;步骤2:推力器开始轨道控制;步骤3:推力器继续轨道控制;步骤4:轨道控制推力器持续开机信号与姿态测量;步骤5:计算偏差姿态;步骤6:判断X轴、Y轴姿态是否偏差:步骤7:X轴正偏差则T2关机并发送信号,X轴负偏差则T4关机并发送信号,Y轴正偏差则T3关机并发送信号,Y轴负偏差则T1关机并发送信号;步骤8:四个信号与轨道控制推力器持续开机信号叠加,判断点火时长满足否;步骤9:为否重复步骤3‑8,为是结束轨道控制。本发明只需要4台对称安装的轨控推力器即可达到同类型6‑14台轨控推力器的效果。
