“…The advantage is that the reliability of each item is easily studied and can be easily applied [26]. The disadvantage is that no information is supplied about the failure mode and therefore about the prognostic for each single item [27]- [28].…”

“…There has been little focus on safety-oriented research to improve MTBF such as reliability of the power system and necessary research and requirements in relation to ground control systems. When looking at safety challenges identified from use of drones (Petritoli et al 2017), the main challenges has been related to Power plant; Ground Control system; Navigation system; Electronic system; Mainframe and Payload. The human factors deficiencies of ground control systems as mentioned in Waraich et al (2013) or Hobbes et al (2014) has not been sufficiently mitigated.…”

This paper discusses state of the art of unmanned aircraft systems (UAS), drones (unmanned aerial vehicle-UAV's) and control infrastructure. The focus has been to explore risks, vulnerabilities and safe use of UAS in industrial operations. The use of UAS has been in rapid expansion in governmental areas (monitoring, military applications) and in the public domain (leisure, photography, transportation, monitoring). Several vulnerabilities have been identified. Few empirical analyses of operations, incidents and successful recoveries are available due to limited reporting. However, safety information from military drone operations are available. The three research questions in this paper are to describe planned use of UAS, major risks and benefits of UAS, and needed research, requirements and rules to improve safety and resilience of operations. We have explored the status of research in Norway, we have performed a literature review of autonomy in aviation, and we have explored relevant cases of industrial transport systems. Our findings indicate that rules and regulations are lagging development of technology and that there is poor focus on major risks related to human factors in engineering, design and operations. To ensure that safety and resilience is in focus from design, there is a need to define scope (i.e. control system as part of UAS) establish functional guidelines (such as human factors guidelines) and improve regulatory frameworks.

“…In mission-critical systems where reliability and safety are a priority, the investigation of the weakest link of the whole system of developed unmanned aerial vehicles (UAV) architecture must be performed [1]. At the moment, most UAVs are developed without such analysis because it is considered that the reliability of all electrical, electronic and electro-mechanic components is sufficient.…”

Reliability Improvement of Power Distribution System for UAV

Unmanned aerial vehicles (UAV), like other complex mechatronics systems, use servomechanisms for the accurate positioning of construction elements. Servomechanisms are stable, reliable and easy to control. However, occasionally they fail and cause issues for the electrical system. In this paper, the authors present a full analysis of the system operations after a specific fault and the consequences of it. The authors propose a test bench and show the experimentation results that contain servo motor electrical parameters at loaded and idle states, the relations to the manufacturer technical specifications, and possible fault detection and elimination solutions. The obtained results could be implemented into existing popular UAV control systems to improve reliability and fault tolerance of commercial products.
