“…Among them, intelligent controllers such as FLC technique is presented as a reliable choice for this mission because since its first appearance in 1965, by Lotfi Zadeh, it witnessed rapid development and replaced almost all conventional techniques a wide range of applications [24].…”

Abstract-This work aims to develop an accurate energy management strategy for a hybrid renewable energy system feeding a pumping station. A developed model under Simulink environment is used to compare the performance of the pumping system when it is only fed by a photovoltaic generator, by a hybrid photovoltaic and fuel cell system and finally by a hybrid photovoltaic, fuel cell and a supercapacitor system. The developed control strategy is based on Fuzzy Logic control technique. Several simulations in different dramatic scenarios of working conditions show that the developed control strategy brought major enhancements in system performance and that the use of the supercapacitor makes economic profits by reducing the fuel cell production during critical solar irradiation periods.

“…[19] In this context, we tried to enhance our system by integrating FL controllers, as shown in Figure 8. by upgrading the existing speed control system with an FL controller and adding a controlled DC-DC controller where it's duty cycle is computed by an MPPT algorithm based on FL technique.…”

“…In this part, we present the different blocks we developed for our controllerFor the Fuzzification phase, based on the work presented in [24], we have divided the first input variable "E", which is the error between the speed reference and the measured one as given in (19), in seven fuzzy variables as shown in Figure 10. The second input variable "dE", which is the variation of the error given by (20), in three fuzzy variables as shown in figure 11.…”

Abstract-This work aims to develop an accurate model of an existing Photovoltaic Pumping System (PvPS) which is composed of an Ebara Pra-0.50T Asynchronous Moto-Pump (AMP) fed by Kaneka GSA-60 photovoltaic panels via a Moeller DV-51 speed drive. The developed model is then used to compare the performance of the system with its original control strategy based on classical indirect vector control strategy using PI speed controller and the proposed new control strategy based on Fuzzy Logic control technique for speed control and MPPT system. The obtained results of comparative simulations, induced in different dramatic variation of working conditions, show that the developed control strategy brought major enhancements in system performance.

“…So the system cannot be easily controlled through conventional feedback controllers with fixed-gain. In addition, the power converter has important variations on its principal parameters, so, classical feedback controllers cannot compensate variations in the parameters of the system, and cannot be adapted to changes in the environment easily Gounden et al (2009). Therefore, nonlinear controller appears as a possibility to control reactive and active power.…”
