自旋导弹周期等效控制力的研究

基于自旋导弹周期等效控制力的形成原理及计算分析,对周期等效控制力周期的概念有了新的认识并提出了计算方法。在对主控信号与线性化信号的幅值比、主控信号的初相位及线性化信号与主控信号的频率比对周期等效控制力的影响深入分析基础上,对合理选择舵系统各参数提出建议。通过实例仿真计算,表明可以实现周期等效控制力对输入主控信号的较理想的线性关系。

Study of periodic equivalent control force of spinning missile

Building theory and computation of the periodic equivalent control force(PECF) of spinning missile are introduced.The concept of period of PECF is newly recognized and computation method is developed.The influences of the amplitude ratio of the main control signal to the linearized signal,the original phase of the mail control signal and the frequency ratio of the linearized signal to the main control signal on PECT are analyzed.Based on these analyses,some advices about selecting parameters are given.Simulation result proves that there is a good linear relationship between the PECF and the main control signal.
