摘要
在现代战术导弹末制导系统中,捷联稳定方案在成本、体积方面与传统的陀螺稳定方案相比具有明显优势,是战术导弹导引头的发展方向,其技术核心是数学稳定平台和捷联稳定算法。研究了半捷联末制导系统中数字稳定平台的控制算法和制导信息提取方法,给出了一套适于工程实现的数字稳定控制算法和相应的目标视线角速度信息获取算法。首先探讨了捷联稳定控制原理,然后提出了一种数字稳定平台的实现算法和目标视线角及视线角速度等制导信息的解算方法,为了克服传感器精度和微分运算不理想所造成的视线角速度计算精度不足,又给出了一种基于导弹-目标角跟踪模型的目标视线角速度滤波模型,最后通过数学仿真验证了上述方法的有效性。
In modern tactical missiles terminal guidance system,strap-down stable scheme is prior to traditional gyro stable scheme in cost and volume,and is a new direction of missile seekers.The critical technique of strap-down terminal guidance system is the so called mathematical stabilization platform and strap-down stable control algorithm.The stabilization control scheme and guidance information extract approach of terminal guidance system with a semi-strap-down structure were discussed.A practical mathematical stabilization control algorithm and the relevant line of sight（LOS） angle rate extract method were devised,which was suitable for engineering implementation.First of all,the principle of strap-down stabilization control was discussed.After that,a new control law of the mathematical platform was described,together with a calculation algorithm of guidance information such as LOS angle and LOS angle rate.Moreover,in order to overcome the deficiency of calculation precision caused by imprecision of sensor′s measurement and non-ideality of differential operation,a practical evaluation filter model of LOS angle rate was given out based on the angle tracking model of a missile to a target.Finally,computer simulations were made which verified the efficiency of above methods.
