Finite-time H₂ performance measure-based strategy design

Based on finite-time H₂ performance measure, a criterion of analysis and design is given and a type of optimal maneuver is designed in consideration of both energy cost and miss distance. In the light of an interceptor guidance law with uncertainties, a method of finite-time robust H₂ performance analysis and a guaranteed cost control criterion are derived, and the guaranteed performance maneuver is designed under the condition of interceptor guidance law with uncertainty. The results show that a substantial maneuvering near the end of penetration process is most effective, and able to cause large miss distance by minimum energy consumption.
