Abstract
In this article several robust control design techniques are compared via their application to the fault tolerant control problem for the lateral/directional motion of JAXA's research aircraft MuPAL-α. The techniques used include: (i) a single, passive-FTC, robust structured H∞ design, (ii) single, active-FTC, robust standard and structured H∞ designs, (iii) manual scheduling schemes from the previous designs, (iv) a self-scheduled structured H∞ design, and (v) a linear parameter varying design. All the designs were implemented in the onboard computer and validated in the so-called Aircraft-In-the-Loop configuration, which entails the operation of the full aircraft in fly-by-wire mode in the hangar. The results show that all the approaches provided acceptable solutions, but with the last two techniques resulting in a more homogeneous performance throughout the fault and command scenarios tested.
