Abstract :
This paper addresses high-precision Mars entry guidance and control approach via sliding mode control (SMC) and Extended State Observer (ESO). First, differential flatness (DF) approach is applied to the dynamic equations of the entry vehicle. The presented control law requires no information on high uncertainties that are estimated by ESO. Finally, simulation results are presented to demonstrate the effectiveness of the proposed approach.
