Proposing moving centroid/RCS control strategy for reentry flight vehicle

Aim. The introduction of the full paper reviews a number of papers in the open literature and then proposes what we believe to be a new control strategy, which is explained in sections 1 and 2. Section 1 gives and simplifies the dynamics model of a reentry flight vehicle with both moving centroid control system and reaction control system (RCS); eqs. (3) and (4) are worth paying special attention to. Section 2 proposes our moving centroid/RCS control strategy; its core is that we analyze the trimming capability and the closed-loop response speed of the moving centroid control system under the constrained actuator; for our control strategy, inequality equations (8) are worth paying special attention to. Section 3 gives a simulation example; the simulation results, presented in Figs. 3 and 4 and Tables 1 and 2, and their analysis demonstrate preliminarily that our control strategy is feasible.
