- 摘要:
- 针对现役捆绑火箭在飞行中发生推力突降的问题,提出了一种基于改进单纯形法的控制分配策略。利用故障前后火箭控制力矩相等的思想,将推力下降后火箭发动机摆角的重新分配问题转化为目标函数约束下的线性分配问题,通过改进单纯形法进行了有效求解。结果表明,偏航角在关机故障发生后可以迅速恢复至平衡状态,滚转角在小幅抖震后同样快速到达稳定,该方法可以有效地改善火箭突发推力下降后控制能力减弱的问题,并维持故障后火箭姿态的平稳,对运载火箭姿态重构研究具有理论意义与工程应用价值。
- Abstract:
- Aiming at the problem of sudden thrust drop for active service strap-on rocket during flight, a control allocation method based on improved simplex method is proposed.Based on the idea that the control torque of the rocket is equal before and after the failure, the redistribution problem of rocket engine swing angle after thrust drop is transformed into a linear distribution problem under the constraint of objective function, which is effectively solved by the improved simplex method.The results show that the yaw angle can quickly return to the equilibrium state after the shutdown failure, and the roll angle can also quickly return to stability after a small buffeting.This algorithm can effectively improve the weakening of the control ability after the sudden thrust drop of the rocket engine, and maintain the stability of the rocket attitude after the failure.The research content has theoretical significance and engineering application value for the attitude reconstruction of launch vehicle.
