This paper describes the ground control system (GCS) of the Smart UAV at the Korea Aerospace Research Institute (KARI). The requirements, configuration and features of the GCS are detailed. And the functions of the pilot bay and observation bay are verified through the analysis of results from the ground and flight tests using a 40% scaled plane. It is also planned to develop a transmission console...
This paper tackles the problem of fault diagnosis and recovery of unmanned aerial vehicles (UAVs) resulting from structural failures (icing). The proposed system consists of two units one for fault diagnosis and another for fault recovery. The goal of the fault diagnosis unit is to detect and estimate the severity of a fault. The recovery unit utilizes information on the estimated fault and adjusts...
The paper shows how the system algebra formal method can be used to analyze the system design of safety critical systems like the Flight Control Systems (FCS) of Jaguar, Airbus A380, and the Boeing 777 aircraft. The capability of the system algebra to verify critical system features like system availability, redundancy, coupling and fault tolerance based on the system states is demonstrated by simulation...
In this paper, an optimal hybrid fault recovery methodology is developed for a team of unmanned vehicles by taking advantage of the cooperative nature of the system to accomplish the desired mission requirements in the presence of faults/failures. The proposed methodology is hybrid and consists of a low-level (an agent level) and a high-level (a team level) fault recovery protocols. The high-level...
