Keywords: helicopter, fault diagnosis, reconfigurable control, swashplate
Using a kinematics model of a helicopter main rotor swashplate, an actuator fault has been numerically simulated and successfully detected using a PCA performed upon flight variables. Then, a method for the reconfiguration of the nominal control law is proposed, based on the minimization of a quadratic criterion.
