In this study, a nonsingular adaptive-gain super-twisting (AGSTW) guidance law is proposed to intercept a target with an impact angle constraint. The stability and convergence characteristic of the AGSTW guidance law are analyzed. The control chattering in system could be mitigated in the presence of uncertainty with unknown boundary. To validate the superiority of the proposed strategy, simulation comparisons with a conventional super-twisting and a sliding mode guidance law are carried out. The results indicate that the proposed AGSTW guidance law could make a missile intercept the target with more favorable miss distance and angle tracking error. The requirement of intercepting different targets could be met in a more satisfactory manner.
