一种改进反坦克导弹高原适应性的非线性控制方法

Non-Linear Control Method on the Adaptability Modification for Anti-Tank Missile on High Plateaus

为了解决某反坦克导弹高原飞行适应性的问题,从分析导弹的频域特性和制导系统参数出发,研究导弹在高原使用时的特性.引入非线性控制方法,对制导回路纵向和横向通道的参数进行改进设计,用数字仿真对改进的有效性进行验证.仿真结果表明,采用非线性控制方法进行设计能够有效提高制导系统在高原条件下的稳定性,改进后的导弹性能满足高原使用要求.

To resolve the inadaptability of an anti-tank missile in its application on high plateaus, the missile＇s characteristics in frequency domain and control system parameters were analysed and the characteristics of the missile used on high plateaus were studied. Non-linear control method was introduced in the modification design of pitch and yaw channel parameters of the guidance loop. The design was validated by numerical simulation. The results showed that the stability of the guided system on high plateaus could be improved effectively using the non-linear control method. The performances of the modified missile satisfied the requirements when used on high plateaus.
