A robust entry guidance law is designed for drag tracking in Mars entry atmospheric flight for low-lifting lander with maximum lift-to-drag ratio of only 0.18. In the flight process the bank angle is the only control variable to be modulated to eliminate the tracking error when considering the initial derivation and parameter uncertainties. Firstly the tough problem of the guidance law design is analyzed which the input coefficient of the drag dynamics equations is uncertain due to kinds of… CONTINUE READING
