— This paper presents a sliding mode control scheme for reconfigurable control of a civil aircraft. The controller is based around a state-feedback sliding mode scheme where the nonlinear unit vector term is allowed to adaptively increase when the onset of a fault is detected. Compared to other fault tolerant controllers which have been implemented on this(More)
— This paper presents a new sensor fault tolerant control (FTC) scheme inspired by a recently developed LPV based sliding mode observer. The robustly reconstructed sensor faults from the observer are used to 'correct' the corrupted measurements before they are used by the existing controller. The modular structure of the sensor FTC scheme allows it to be(More)
Sliding mode methods have been historically studied because of their strong robustness properties with regard to a certain class of uncertainty, achieved by employing nonlinear control/injection signals to force the system trajectories to attain in finite time a motion along a surface in the state-space. This paper will consider how these ideas can be(More)
