TADC: a new three-axis detumbling mode control approach

Abstract

A new three-axis detumbling mode control approach, namely TADC in the present research, is investigated to deal with a spacecraft, in a short period of time. In a word, the study considers the problem of detumbling by means of system modelling, while the proposed control approach in agreement with the simulation results can be of novelty with respect to the other related potential benchmarks. The approach proposed here plays an important role in this area to adjust angular velocities in the three axes regarding the system under control to be desirable. In some cases, to guarantee the system stability in the process of missions, the whole of angular velocities are to be accurate. In fact, it aims us to organize a number of programmed maneuvers including the orbital, the thermal and so on to be efficient. The idea behind the approach is organized in line with a linear control approach, since the pulse-width pulse-frequency modulator is employed in association with the control allocation to cope with a set of on-off thrusters. Hereinafter, the number of these on-off thrusters may be increased with respect to the investigated control laws to provide overall accurate performance of the spacecraft through the control allocation. The effectiveness of the approach investigated here is finally considered by organizing four scenarios of the experiments and also comparing the outcomes with a number of potential benchmarks.
