一种新的闭路制导导引方法

闭路制导方法是一种实用的方法误差比较小的制导方法。其中,如何将实际速度导引到需要速度至关重要,通常的闭路制导导引方法在关机点附近不稳定,会产生一定的方法误差。为了避免这种导引不稳定的影响,本文给出了一种采用目标瞬时方位角为基准的新型闭路制导导引方法。通过仿真计算,证明该方法关机点附近导引稳定,导引引起的方法误差较小。

A New Guided Method of Close-loop Guidance

Close-loop guidance is a kind of method with practicality and less error.It is very important to lead actual velocity to required velocity in close-loop guidance.The general close-loop guidance guided method is unstable round shut down point which will produce some method error.In order to avoid the influence of the instability,a kind of new close-loop guidance guided method based on target moment azimuth angle is put forward.Simulation proves that the new guided method is stable round shut down point and the method error is less than that of original methods.
