文摘

Demonstrated improvements in trajectory tracking using a robust entry guidance law. Created guidance law using terminal sliding mode and second-order differentiator. Compound control improves guidance tracking , even with imperfect nonlinear dynamic. Nonlinear compound control demonstrated to reduce guidance tracking error.
