Performance-Involved Coupling Effect-Triggered Scheme for Robust Attitude Control of HRV

This article investigates the relationship between the tracking performance and coupling effect for attitude tracking issue of hypersonic reentry vehicle (HRV), and proposes a performance-involved coupling effect-triggered robust control scheme. The main feature of the article lies in that the influence of the coupling effect on the performance is discussed via a defined performance-involved coupling effect indicator. Consequently, the proposed control ensures the transient performance within the prescribed limitation in all phases, and the better transient performance is achieved with the help of the sliding mode control and disturbance observer technique enhancing the robustness. Comparison simulations and Monte Carlo tests under coefficients perturbation on the HRV system demonstrate the effectiveness of the proposed control strategy.
