Intelligent fault-tolerant controller of quadrotor against GPS faults

Quadrotor has been applied for various civil aviation and military services. Since its wide applications, this raises a safety concern. In this paper, we present a fault-tolerant control (FTC) scheme that can be used to handle GPS faults. The proposed control uses neural networks to learn dynamical behaviors and estimate the GPS. Simulation studies have been given to illustrate the effectiveness of the proposed method.
