Abstract

In this paper, a combined station-keeping, attitude control and momentum dumping strategy for a low-thrust spacecraft in an Earth - Moon !2 halo orbit is explored. The problem is formulated as a constrained, non-linear optimal reference tracking problem and a computationally efficient Tracking-oriented Model Predictive Static Programming (T-MPSP) technique is used to obtain the desired thrust forces and reaction wheel torques. The formulation addresses various practical limitations which include saturation in thrust, reaction wheel speeds and attitude constraints. The T-MPSP technique transforms the nonlinear reference tracking problem into a quadratic programming problem and is implemented using a receding horizon strategy to incorporate robustness against various parametric and actuator uncertainties of the spacecraft. The methodology involves calculation of sensitivity matrices which are done in a computationally efficient manner owing to their recursive nature. Finally, the capability of the technique is demonstrated using numerical simulations. © 2021 by the International Astronautical Federation (IAF). All rights reserved.
