冲压发动机的性能高低很大程度上取决于它的控制品质。控制系统通过设置各种极限函数确保冲压发动机在外部干扰和内部扰动下可靠稳定工作,并结合任务特点采用不同的控制策略进行合理的调节,充分发挥出冲压发动机的性能。本文研究了3种不同控制参数下冲压发动机的稳定工作范围。针对不同的飞行任务的要求,研究了常用的控制策略下冲压发动机的控制路径。
The performance of a ramjet engine depends largely on its control quality. By setting various limit functions, the control system ensures that the ramjet engine can work stably and reliably under the external disturbance and the internal disturbance. According to the characteristics of the task, different control strategies are used to adjust the performance reasonably and the performance of the ramjet engine is fully exerted. This paper studies the stability of the ramjet engine under three different control parameters. According to the requirements of different missions, the control path of ramjet engine under common control strategy is studied.
