This paper presents a fuzzy feedback control system for DC voltage regulation of a phase-controlled three-phase rectifier. The controller operating range covers both the continuous conduction mode and the discontinuous conduction mode. In the latter operating region, the converter characteristics are highly nonlinear and too difficult to be modeled mathematically. For this reason, a fuzzy control design based on a heuristic representation of the process is proposed. The digital model of the controller is, first, established using the Fuzzy toolbox of Matlab/Simulink, then compiled in the OPAL RT-Lab OP4100 special device that allows real-time control. For experimental validation, the designed fuzzy controller is applied to a 3kW laboratory prototype three-phase thyristor-bridge feeding an inductive load. The tracking and regulation performances of the control system are tested, and the corresponding data are plotted.

“…Consequently, there was a great room to, first, improve the ITU -R techniques to keep them accurate at higher frequency operations, and, second, to decouple them from the fifteen years average data provided by ITU -R [10,15,16,29]. However, if we are able to make them work with predicted weather data, those techniques could help satellite service providers achieve better operation, as much as they helped in the system design in the past [7,9,30,31].…”

“…In this section, we extend the analytical methods for estimating gaseous attenuation presented in ITU -R Recommendation P. 676. This method had been discussed in great deal in our papers [3,31] to present the variations of gaseous attenuation with the changing of rainfall rate, propagation angle, and frequency for a given temperature, pressure, location, etc. The key point is that gaseous attenuation depends on meteorological conditions created by the distribution of temperature, pressure, and humidity along the transmission path.…”

“…The cumulative distribution of tropospheric scintillation is based on monthly or longer average ambient temperature t (Celsius). This distribution reflects the specific climate conditions of the site [3,31,57]. The following is a general technique for estimating scintillation attenuation as a function of rainfall rates and propagation angles.…”
