In this paper, a nonlinear and robust guidance system against target maneuvers has been designed. For this purpose, first a new high order sliding mode algorithm is proposed. The designed guidance law with this algorithm generates a smooth acceleration command that guarantees collision with target. In this algorithm, unlike previous high order sliding mode theories, the stability of close loop system in the presence of uncertainty is guaranteed, therefore the observer is not required for estimation of target maneuvers in the proposed guidance law. For designing two point guidance law using this algorithm, a sliding variable has been introduced using relative lateral velocity. Designed guidance law generates acceleration commands that guarantee convergence of sliding variable. Simulation results show the better performance of proposed guidance law in comparison with other guidance laws.
