Abstract

In this paper, the finite-time trajectory tracking control problem for Mars landing with disturbances is addressed. To improve the accuracy of Mars landing, a new nonlinear entry guidance law for low lift landers has been developed. The High-Order Sliding Mode Control(HOSMC) for a tracking a reference trajectory is proposed. The guidance method is based on HOSMC theory adapted to the problem of entry guidance. The HOSMC has been adapted to account for the specific 2-sliding modes exhibited by the longitudinal motion of the entry vehicle, using bank angle control for following a reference trajectory. The global stability nature of the HOSMC law is proven by using a Lyapunov-based approach. Extended state observer are applied to estimate the disturbance, by which sliding mode controllers are designed combing the two approaches respectively to force the state variables of the closed loop system to converge to the reference trajectory. Also, simulation results are presented to illustrate the effectiveness of the control strategy.
