基于INA方法的旋转导弹解耦研究

Research on INA Method-Based Rolling Missile Decoupling

在双通道控制旋转导弹进行解耦研究中,为解决系统的准确跟踪问题,采用INA(逆奈奎斯特阵列)方法,对双通道控制旋转导弹进行仿真建模和耦合性分析,推导出了准弹体系下传递函数的准确表达式。对逆传递函数矩阵的奈奎斯特图进行了耦合性分析,设计出了预补偿器,反馈矩阵以及比例积分控制器。通过仿真验证了双通道的交连情况和解耦算法的有效性,为双通道控制旋转导弹控制系统分析与设计提供了新的思路。

This paper studied decoupling control for double-channel control rolling missile.The INA method was used to solve the problem of accurate tracing,and the coupling character was analysed for double-channel control rolling missile.The accurate form of body motion expression under quasi-body coordinate was deduced.After analysing the Nyquist chart of a inversing transfer function matrix,the pre-compensator,feedback matrix and PI controller were obtained.The simulation results verified the quality of the scheme introduced above.TheINAmethod was suitable for the simulation of coupling analysis of double-channel control rolling missile.This paper presented a new method for analysing and designing the missile control system.
