Partial integrated guidance and control method for the interception of nearspace hypersonic target

The interception of the hypersonic weapons in near space is the main problem considered in this paper. Different from traditional interception cases, the designed interceptor is assumed to have much lower speed than its target and very limited maneuverability in the near space atmosphere. To deal with this problem, a two-loop Partial Integrated Guidance and Control (PIGC) scheme using high order sliding mode control method is introduced in this design. More specifically, an integrated full state feedback guidance loop and an inner state feedback control loop together provide a quick and stable response to the target maneuver. At last numerical simulation results are given to demonstrate the superiority of the proposed method.
