整体式冲压超音速飞航导弹的自适应控制

On Adaptive Control of Surpersonic Cruise Missile Powered with Integrated Ramjet

采用导弹总体、气动、动力、控制和弹道一体化设计方法，研究了超音速整体式冲压发动机飞航导弹的控制问题。引入了自适应控制规律，利用该规律，可全面满足发射高度在大范围内变化时的所有战术技术要求．

There have been some studies in Chinese journals on air-to-ship supcrsonie cruise missile which has integrated ramkt as its powcrplant. In this paper, we explore a more complicated situation' very big variation in launch height.There arc mainly two factors that make the situation more complicated: (1) Stringent tactical requirements. The air-to-ship missile must in a very short time drop to near the sea surface,and yet,safcly turn into approximately horizontal flight.(2) Restrictions imposed on flight attitude by the powerplant,for example, angle of attack must be within 6 degrees of its stipulated value.To deal with the two main difficultics,the authors find it necessary to include an adaptive control law in height loop. Then the authors design a trajectory with inflection point that does appear to overcome the two difficulties.Simulation tests indicate that the authors' proposal is feasible.
