N2 - Aiming at intercepting maneuvering target with desired impact angle in the three-dimensional (3D) space, a novel integrated guidance and control (IGC) law based on command filter backstepping control (CFBC) and finite-time extended state observer (FTESO) is proposed. A full-state coupled IGC design model including model uncertainties, target maneuver and channel coupling is established at first. To estimate target accelerations, a FTESO is designed to estimate the target maneuver and model uncertainties. The CFBC method is used to achieve angle control and hit the target accurately. And it also effectively avoids the 'explosion of complexity' problem. Moreover, the uniform boundedness of the closed-loop system is proved by Lyapunov theory. Finally, numerical simulations are used to verify the effectiveness of the proposed method.
