Backstepping Control Based on Constrained Command Filter for Hypersonic Flight Vehicles with AOA and Actuator Constraints

An antisaturation backstepping control scheme based on constrained command filter for hypersonic flight vehicle (HFV) is proposed with the consideration of angle attack (AOA) constraint and actuator constraints amplitude rate. Firstly, HFV system model divided into velocity subsystem height subsystem. Secondly, to handle AOA constraint, a constructed limit retain its differentiability. And range set in advance via prescribed performance method guarantee that tracking error meets conditions transient steady performance. Thirdly, combined auxiliary constraints, which ensures input limited requirements rate, stable. In addition, errors are proved be ultimately uniformly bounded Lyapunov stability theory. Finally, effectiveness verified by simulation.
