K1 Motion control of the primitive body exploration spacecraft in approach and touchdown phase applying Model Predictive Control

Abstract

JAXA is planning new asteroid exploration mission after "HAYABUSA". This planned mission requires much higher guidance accuracy in approach and touchdown phase than previous mission since it is expected to touchdown inside of the newly made crater. For position controller design Model Predict Control (MPC) which can consider limitations in control input and predict future state is applied in this paper. The performance and usefulness of this control algorithm is evaluated through numerical simulation.
