In this paper, we describe a method for relating the precision in phase shift measurements to the navigation areas in which that precision is reached so that a coverage map is built, setting a signal-to-noise ratio (SNR) threshold level that depends on that phase precision. The method brings a novel approach to linking different areas in robotics and is applied to a mobile-robot (MR) local positioning...
A method for error correction in a phase-shift measuring system based on an I/Q demodulator for robot positioning applications is proposed. Non ideal effects of the system can make inaccuracy rise unacceptably. These effects are modelled so that the error-correction process reduces the error down to 1-1.5 cm, as shown with real measurements, which is highly satisfactory.
This paper proposes a new MPPT algorithm (`maximum power point tracker') for photovoltaic panels (`PV') with NPC converters (`neutral point clamped'). One of the characteristic of this proposal is that it is not necessary to modify the voltage references in order to know the state of the MPP (`maximum power point'). The fundamentals are based on the use of the existing ripple in the NP (`neutral point')...
