Low-Thrust Guidance Scheme for the Spacecraft using B-plane Targeting and Lyapunov Feedback control
Dong-Hyun Cho,Hyochoong Bnag 제어로봇시스템학회 2012 제어로봇시스템학회 국제학술대회 논문집 Vol.2012 No.10
In this research, the trajectory correction maneuver(TCM) is proposed for the spacecraft has an interplanetary mission with low-thruster such as electric propulsion system. During the trasfer phase of the interplanetary mission, the trajectory error occurs due to the influence of external perturbation forces. Thus, the TCM is required to reduce this error. In the previous researches, the TCM techniques was focused on the impulsive thrust. However, the delta velocity for the TCM is relatively small, and the technology of the electric propulsion system is brilliantly developing. For these reason, in this paper, the TCM for the continuous thruster is suggested. For this suggested TCM, the B-plane targeting method widely used in the interplanetary mission is adopted as a target parameter, and the Lyapunov feedback control is also used as a low thrust guidance scheme.

For the interplanetary mission, the spacecraft must require the trajectory correction maneuver (TCM) to reduce the trajectory error due to the influence of unexpected external perturbation forces. There are many kinds of researches focused on these TCM techniques for the impulsive thrust. Among them, the B-plane targeting method is mainly applied to the interplanetary mission as TCM method. However, there are brilliant developments in the propulsion systems; especially the electrical propulsion system is adopted in some spacecraft. Thus, it is necessary to design the TCM algorithm for such low-thruster for future interplanetary missions. Therefore, in this paper, the TCM algorithm for the low thrust such like electrical propulsion system is suggested to correct the target B-vector and target time to closest approach (TCA). To design the low thrust guidance scheme, the Lyapunov feedback control is used in this paper.
