旋转反坦克导弹制导系统精度改进研究

为了解决某反坦克导弹续航段长时间偏离在瞄准线右侧飞行的问题,从分析导弹的频域特性和制导控制系统参数出发,研究问题发生的机理,引入非线性控制方法,在频域范围内对制导回路的纵向和横向通道校正环节及参数进行改进设计,用数字仿真验证改进的有效性。仿真结果表明,改进后的导弹性能,满足战绩使用要求。

Study of Precision Improving for Spinning Anti-tank Missile''''s Guided System

To eliminate the anti-tank missile's deep flight on the right side of sight line,based on analyzing the missile's characteristics in frequency domain and control system parameters,studying the mechanism,non-linear control method was introduced in the modification design for pitch and yaw channels' correctors and their parameters of guidance loop in frequency domain.Numeric simulation was used to validate the modification methods.The results show that the performances of the modified missile satisfy requirements.
