摘 要：This paper presents an active fault-tolerant linear parameter varying（LPV） autolanding controller for a civil aircraft subject to elevator failure during landing maneuver. Firstly, an LPV autolanding controller is designed to assure the acceptable tracking performance and stability of the civil aircraft’s autoland. The scheduling parameter is chosen as the estimation of the elevator failure factor. Secondly, a two-stage Kalman filter estimator is designed to estimate the failure factor. Then, the LPV controller and the estimator are integrated to achieve the active fault-tolerant performance. Finally, simulations of the autolanding control system show that a superior fault-tolerance can be achieved.
