Performance-Guaranteed Attitude Tracking Control for RLV: A Finite-Time PPC Approach
IEEE Transactions on Aerospace and Electronic Systems(2024)
Abstract
This paper presents a finite-time prescribed performance control (FPPC) scheme for the attitude tracking problem of reusable launch vehicles during the terminal area energy management flight. The proposed control solution offers the possibility to enforce the bound performance function to zero. The attitude tracking error is thus able to reach zero, and thanks to the proposed control theory, it occurs in finite-time. Besides, the proposed control framework mitigates potential singularity issues near the boundary. The robustness of the proposed attitude control loop against uncertainties is demonstrated using the interval theory. Parameters tuning of the control algorithm is also discussed in details, some simulations demonstrate the efficiency of the proposed approach.
