Abstract :
The potential uses for Unmanned Aerial Vehicles (UAVs) is vast. However, much of their potential can only truly be unlocked by giving them a higher level of autonomy. This paper focuses on an autonomous Collision Avoidance System using Specific Acceleration Matching, which is termed the `CASSAM´ in this paper. This approach is being studied as it may prove an effective means to increase the level of autonomy of UAVs. The paper presents the design of the CASSAM first by modelling the UAV dynamics and then by designing suitable control algorithms. Simulation results in 2D show that it is a viable option to address the UAV collision avoidance problem having effectively evaded threats with minimal control effort.
