This paper characterizes the effect of propellant slosh on the performance of an active stabilization control system for the two-two-and-over symmetric landing mode during touchdown. Generalized impulse and momenta theory is used to model the instance when the landing leg strikes the ground as an inelastic collision event. For active stabilization, a rate damping controller is used to stabilize the attitude of the vehicle via onboard reaction control system. Simulation results are shown comparing the performance of the control system with and without slosh dynamics.
