摘 要:为分析隔离度对制导系统的影响,提出了隔离度引起的寄生耦合问题。首先建立了制导回路数学模型,讨论了寄生耦合的产生机理。接着,基于归一化方法和劳斯判据,提出了耦合回路的稳定性约束,研究了隔离度对制导回路稳定性的影响。最后选取典型参数,分析了寄生耦合效应的存在,改变了制导系统的响应特性。研究结果表明,为保证快响应寻的制导系统的性能最优,必须进行制导系统的匹配性设计。In order to analyze the effect of disturbance rejection rate on guidance system, the problem of parasitic coupling which caused by disturbance rejection rate is presented. Firstly, based on mathemati- cal model of guidance loop, the causing reasons of parasitic coupling are discussed. Secondly, with nor- malized method and Routh criteria, stable region of the coupling loop is put forward and the effect of dis- turbance rejection rate on stability of guidance loop is studied. Lastly, under the given characteristics pa- rameters, it demonstrates that the response of guidance system is changed in existence of parasitic coupling effect. The investigation results show that guidance-loop matching design must be done to guarantee the fast target tracking systems with optimal performance.
