This paper proposes a holistic actuator fault tolerant
control scheme and validates it using the Japan Aerospace Exploration Agency’s Multi-Purpose Aviation Laboratory (MuPALα) Aircraft-in-the-Loop (AIL) platform. The motivation for this
work is to increase the Technology Readiness Level associated
with fault tolerant control technology, whilst improving the
sustainability of future aircraft. The overall scheme uses bespoke
sliding mode observers at a (local) individual actuator level
to assess the health and the effectiveness level of each of
the actuators. These estimates are aggregated and used in the
control allocation mechanism to distribute a virtual control
signal, designed using sliding mode control concepts, to the
physical actuators. The overall closed-loop system stability is
rigorously analysed. The validation results show that the actuator
effectiveness is well reconstructed and near nominal lateral directional control performance is retained in the face of a class
of actuator faults.
