Autonomous flight at low altitude using light sensors and little computational power

Dario Floreano, Jean-Christophe Zufferey, Antoine Beyeler

The ability to fly at low altitude while actively avoiding collisions with the terrain and objects such as trees and buildings is a great challenge for small unmanned aircraft. This paper builds on top of a control strategy called optiPilot whereby a serie ...

Weight and efficiency optimization strategy of an interleaved DC-DC converter for a solar aircraft

Alfred Rufer, Philippe Barrade, Yannick Louvrier

Today, energy saving is one of the main objectives for engineers. In the case of mobile applications, energy can be saved by two different ways. First, decreasing the total masse of the system, and second, increasing the efficiency of the overall system.Th ...

Self-Sensing Methods from MEMs to Solar Aircraft Motors

Yves Perriard, Miroslav Markovic, Omar Scaglione

In order to control the speed and/or position of permanent magnet (PM) motors, they require position sensors. Basically, the auto-commutation needs 3 sensors for a 3-phase motor. In micro-motors, as there is no space for the sensors, self-sensing must be u ...
