Research and simulation on new robust guidance law of missile

With analyzing the missile-target relative line-of-slight (LOS), a robust guidance law of homing-missile was derived by L₂-gain theory. When the target acceleration bound and guidance factors varied, this robust guidance law shows stronger robustness, therefore the precise of measuring target acceleration is not required. The new guidance law was simply achieved, with line-of-sight measurement only. In simulations, the same initial conditions were used to analyze the robustness and precision of the proposed law compared to PNG. For a maneuvering target with angular noise, the proposed law works better than the PNG, when partially simulating, the proposed law is no better than the PNG.
