Fault tolerant control of a quadrotor based on parameter estimation techniques and use of a reconfigurable PID controller

This paper focuses on the fault tolerant control for a quadrotor. In this paper, both a complete dynamic model of quadrotor and a simple reconfigurable PID controller are presented. Besides, FDD and FTC techniques are developed using parameter estimation techniques. The proposed approach allows to detect and to diagnose faults in a rotor. The main contribution of this article relies on the detailed modelling of a quadrotor and a use of parameter estimation techniques including an expert method based on the knowledge of the system and a logical reasoning.
