摘要
首先对传统的比例导引控制系统进行了分析,分析结果表明,传统的比例导引方法对导弹剩余飞行时间的估计依赖性强,剩余飞行时间估计误差将大大降低制导性能,甚至造成导弹脱靶。为了解决这一问题,提出了一种降低敏感度制导律,建立了该改进制导律的数学模型并进行了仿真,仿真结果表明,该制导律对剩余飞行时间误差敏感度低,并能够提高制导性能。
In this paper,the traditional proportional navigation control system is analyzed and we find that the traditional proportional navigation guidance law is sensitive to residual flight time,the residual flight time estimation error may cause significant degradation in the performance of the PN guidance law.So we design a new guidance law which is called Reduced Sensitivity guidance Law（RSL） to solve the problem.The simulation results show that the RSL method is insensitive to the residual flight time estimation error and the performance of the RSL guidance law system is improved.
