Abstract

Attitude control of the lunar lander is achieved through reaction control system (RCS). RCS works in pulsing mode and needs control allocation system which takes care of attitude tracking with minimum fuel consumption. Most of the control allocation techniques are based on pulse modulation technique, which are difficult to implement for RCS, where torques generated by RCS are generally coupled with each other. In this paper, eight unilateral pulsing mode attitude thruster for attitude correction of lunar module targeted for soft landing is presented. Linear programming based control allocation technique for RCS has been discussed, which gives fuel optimal solution with accurate tracking as a constraint. Landing specific simulation is done to validate the control system. (C) 2018, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd. All rights reserved.
