Abstract

Abstract: Abstract：A robust entry guidance law with finite time convergence is designed for dragtracking in this paper. The bank angle is regarded as the control variable. First, a robust sliding mode control (SMC) method, which can guarantee the finite time convergence, is proposed for a class of nonlinear systems with uncertainties and disturbances. Then, after the drag dynamics is given, the finite time guidance law is designed based on the proposed SMC method. A 1 000run Monte Carlo simulation shows the effectiveness of the presented approach.

Key words: Keywords：entry vehicle, dragtracking, sliding mode control, finite time convergence, Monte Carlo simulation
