Abstract: | In this paper, a finite-time convergent sliding-mode guidance law with terminal impact angle constraint is presented. The guidance law insures that the line-of-sight angular rate will converge to zero before the final time of the guidance process. Meanwhile the flight-path angle will meet the terminal impact angle requirement. Based on the finite-time convergence stability theory and the variable structure control theory, the finite convergence time is determined. Finally, the simulation results show that the guidance law is effective. |
