Embedded Implementation of Improved IFOC for Solar Photovoltaic Water Pumping System Using dSpace

In this chapter, a proposed indirect field oriented control (IFOC) based induction motor drive for solar PV water pumping system (SPVWPS) powered by the two-level inverter is presented. The proposed scheme aimed at enhancing the performance and the dynamic response of the PV system. It consists of operating the induction motor at optimal reference flux which leads to improve the overall efficiency of the SPVWPS. The proposed IFOC scheme will be investigated experimental implementation using the dSpace DS1005 board. The proposed SPVWPS is evaluated and compared with the conventional IFOC under reel climatic conditions. Experimental results illustrate the effectiveness of the suggested control strategy in terms of pumped water, minimization of absorbed current, and overall efficiency.
