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,并考虑在制导算法中引入导弹的实际加速度补偿量进一步改善制导回路的性能,设计了制导系统校正算法。通过线性化模型对其性能进行了数字仿真,仿真结果表明该算法能够降低目标机动时所产生的脱靶量。最后,通过具有天线罩误差效应的线性化制导系统模型,对校正算法增加前后的制导控制系统稳定性进行了对比仿真分析。In order to meet the rapid requirement of the guidance system when the air-to-air missile against high maneuvering target,by using the classical control idea that feedback/feedforward control theory can improve the transient and frequency response,and considering the actual acceleration compensation of missile in the guidance algorithm to further improve the performance of the guidance loop,the guidance system correction algorithm is designed.The performance of the algorithm is simulated by linearization model,the simulation results show that the algorithm can reduce the miss distance when the target maneuvers.Finally,through the linearized guidance system model with radome error effect,the stability of the guidance and control system before and after the correction algorithm is added is compared and simulated.
