Controle tolerante a falhas de um sistema de propulsão de hexacópteros

Abstract

This dissertation aims to develop the fault tolerant control of a propulsion system of hexacopters, which intends to keep it in good flight conditions. Initially, it’s presented the modeling of the system, considering the kinematic and dynamic model of the aircraft where the gravitational and propulsion forces are considered. Failures in propulsion systems are inserted to the system and when detected, the system can be operated with the new PID tuning, keeping it in flight. Finally, the results are simulated and analyzed using performance indices as IAE, ISE and ITSE, making possible to perform the feasibility study of the time limit that a technique for detecting and identifying faults have available to find which propulsion system meets problems. The results were satisfactory showing to be a possible technique to be implemented in the aircraft developed.
