摘要
针对空空导弹抗目标大机动时,制导系统持续增加的快速性需求,利用反馈/前馈控制信号可提高瞬态和频率响应的经典控制思想,以及在制导算法中引入导弹的实际加速度补偿量以改善制导回路性能的方法,设计了制导系统校正算法。然后,通过线性化模型对制导系统校正算法的性能进行了数字仿真,仿真结果表明系统校正算法能够降低目标机动时所产生的脱靶量。最后,在仿真环境中加入导引头测角噪声,对校正算法增加前后的制导控制系统性能进行仿真和对比分析,基于分析结果对噪声环境下的校正算法进行了优化。
When air-to-air missile strikes a large maneuvering target,the increasing speed of guidance system is needed.Based on the classical control theory,the transient and frequency response can be improved by using the feedback/feed-forward control signal,the performance of the guidance loop can be further improved by introducing the actual acceleration compensation.With these methods,the guidance system compensation algorithm is designed.The performance of the guidance system compensation algorithm is simulated by linearization model,the simulation results show that the guidance system compensation algorithm can reduce the miss distance caused by target maneuvering.Finally,the angle measuring noise of the seeker is added.The performance of the guidance control system before and after the correction algorithmis simulated and compared,and the correction algorithm under the noise enviroment is optimized based on the analysis result.
