摘要
基于传统脉冲发动机点火控制逻辑,从理论上分析了点火相位特性和剩余误差,发现当脉冲发动机数量不足时,存在着较大的剩余误差。提出了一种在脉冲发动机数量不足条件下,以修正后剩余弹道偏差所需脉冲发动机数量最小为目标的点火相位控制优化策略,并采用6自由度弹道仿真验证了方法的有效性。
The firing phase angle characteristics and residual error were theoretically analyzed on the basis of traditional firing control logic of pulse jets. It has been found that there may be a large residual error when the number of pulse jets is of shortness. An optimization strategy for the firing phase angle control was presented, which makes the number of pulse jets b＇e minimum for the residual trajectory deviation after correction under the condition that there are not enough pulse jets. Finally, the method was verified by the 6-degrees of freedom trajectory simulation.
