摘要
研究适用于近距格斗空空导弹的滚-仰式导引头跟踪原理。根据导引头探测器上目标的位置信息,导引头稳定平台状态及导引头与弹体间的相对运动关系,导出了导引头跟踪框架角误差信号的数学模型,以实现导引头的闭环控制。然后结合导引头的控制特点,完成了导引头控制系统的设计。结合工程实际应用,研究了导引头跟踪框架角误差简化公式的适用性,研究表明,简化公式和精确公式给控制系统性能带来的主要差别在于由简化公式得到的俯仰通道控制系统较精确公式得到的俯仰通道控制系统稍慢。其造成的影响可以通过俯仰通道与滚转通道带宽比的优化设计来补偿。分析表明,实际应用中可以采用简化公式求导引头跟踪框架角增量,实现导引头的闭环控制。
The tracking principle of roll-pitch seeker well-suited for short-range combat air-to-air missile was researched. According to the target angular coordinates on detector, geometry of roll-pitch seeker and its location relative to the missile, the modeling of tracking gimbal angles error signals were derived to realize the close loop control of the roll-pitch seeker.And combined with the control characteristic of roll-pitch seeker, the control system of roll-pitch seeker was designed.For the actual application, the simplified modeling of tracking gimbal angles error signals was proposed. The difference was that the pitch loop control system constructed by the simplified modeling was slower than the precision one＇ s.Sequentially the effect of the simplified modeling could be compensated by optimizing bandwidth ratio of pitch and roll loop. The analysis results indicate that the simplified modeling can be adopted in actual application.
