Evader maneuver on consideration of energy consumption in flight vehicle interception scenarios

To solve the problem of interception avoidance of flight vehicle, this paper comprehensively considers miss distance, energy consumption and prediction uncertainty on the final time of interception by a finite-time H∞H∞ performance measure, and designs optimal energy consumption maneuver. An optimal interception against optimal evader maneuver of flight vehicle is also presented. The results show that the best evader effect will be achieved under condition of a large amplitude evader maneuver at the end of interception if the flight vehicle can predict the final time of interception accurately, and a large interception miss distance will be gained at a relatively small energy consumption.
