A Longitudinal Compound Guidance Law for a Guided Bomb with INS/Satellite Positioning System(INS/SPS) based on Optimization Theory

Hang Wang

Abstract

Based on the analysis of the characteristics of the bomb and working mechanism of INS/SPS,a compound guidance law is proposed,consisting of midcourse guidance and optimal terminal guidance.In the midcourse guidance phase,best attack angle is obtained at real time,to get maximum value of lift-drag ratio.In terminal guidance phase,a big-enough trajectory angle of impact point is gained with least energy,according to optimal control theory.Larger range and better killing power of GB is correspondingly realized.And simulation is carried out for a certain type of GB,and simulation results confirm the efficiency of the compound guidance law,which in turn provide valuable basis for the design of GB control and guidance system.
