Résumé

This paper deals with the development of Integrated Guidance and Control (IGC) law for a class of hypersonic interceptors which are equipped with the infrared seeker. Since in practice the line-of-sight (LOS) angular rates are difficult to measure for this class of hypersonic interceptor, an unknown state observer based on high order sliding mode technique is firstly proposed to estimate the unknown state and disturbance precisely with the partial measurable state. Then, an adaptive Incremental Backstepping (IBS) scheme that relies on estimates of the LOS angular rates, angular acceleration measurements of the current control deflections is proposed to achieve robust tracking of a maneuvering target. The stability analysis of the closed-loop system is also conducted. At last, a series of simulation results are presented to show the great potential of the proposed IGC method in interception accuracy, even if the LOS angle rates are unmeasurable. It is shown that the proposed scheme is not only more robust to uncertainties in the hypersonic interceptor dynamics compared to conventional IGC, but also has better trajectory characteristic with less control effort. The hit-to-kill interception is achieved in the simulation results.
