Abstract

The determination of switch time of lateral thrust for the blended control missiles in the situation of target maneuver is researched. Firstly, the characteristics, which are finite time, non-zero initial conditions and strongly time-varying, are analyzed for the terminal guidance system. Based on this, the linear time-varying(LTV) model is established for terminal guidance system. Secondly, the finite time generalized H₂ performance measure and corresponding criterion are given for a blended control system. Finally, the Relationship between zero effort miss distance (ZEM) and switch time of lateral thrust is analyzed under different target maneuver (CA, Singer, Weaving), which provide the basis for the determination of switch time of lateral thrust for the blended control missiles.
