摘要
针对导引头稳定系统的扰动隔离度问题进行了深入研究,介绍了扰动隔离度的概念及相关数学模型,讨论了影响隔离度的各种因素,分析了弹体扰动作用的本质和摩擦力矩的关系,最后就探测器处理延迟对扰动隔离度的影响进行了全面的分析研究,并提出了一种基于Smith预估器的延迟影响补偿控制方案,通过仿真说明了该方法的有效性。
The concept of disturbance rejection rate and its mathematical model are introduced. Some factors that have influence on the rejection rate are discussed. The essentiality of missile body disturbance action and its relationship with moment of friction are analyzed. Finally, the influence of detector process delay on distur-bance rejection rate is studied and analyzed in detail. A new compensation algorithm based on Smith predictor is proposed, and simulation result showed the effectiveness of the method.
