Passive Fault Tolerant Lateral Controller Design For an UAV

IFAC-PapersOnLine, 2018
Abstract In this study a passive lateral fault tolerant controller for an UAV is designed using dynamic inversion (DI) method and robust integral of the signum of the error (RISE) techniques. The details of the methods are summarized. As the reference model of the tracking controller, UAV controlled by feedback type controller is used and the control
