This study proposes a formation control scheme for a group of quad-rotor aircrafts. The formation is realised by considering a constant altitude for the group of aircrafts. The authors propose a stability analysis that considers the aircraft group as a large-scale interconnected linear system in order to compute the value of the formation gain that guarantees its stabilisation. The control scheme for the group is based on the potential field theory, whereas the stabilising control law for each rotorcraft is done through nested saturation functions. The author also propose repulsive functions in order to guarantee obstacle avoidance. The repulsive functions take into account the attractive forces to compute, in a suitable way, the repulsive forces. Simulation results emphasise the effectiveness of the proposed control scheme. © 2012 The Institution of Engineering and Technology.

The power systems are exposed to various types of faults that can cause disturbances. A fast restoration of faulted elements can reduce the possibility of a major disturbance, but it is necessary to determine the location of the fault. This paper describes a method for the fault location diagnosis combining information of synchronized phasor measurements and the principal component analysis as statistical analysis of the data. Results are presented of the location of failure diagnosis for various cases using the IEEE 39 bus system. © 2003-2012 IEEE.
