In recent years, the improvement of photovoltaic water pumping system (PVWPS) efficiency takes the considerable interest of researchers due to its operating based on cleaner electrical energy production. In this paper, a new approach based on fuzzy logic controller incorporating loss minimization technique applied to the induction machine (IM) is developed for PVWPS applications. The proposed control selects the optimal flux magnitude by minimization of the IM losses. Moreover, Variable step size perturb and observe method is introduced. The suitability of the proposed control is approved by reducing the absorbed current; therefore, the motor losses are minimized and the efficiency is improved. The proposed control strategy is compared with the method without losses minimization. The comparison results illustrate the effectiveness of the proposed method based on losses minimization regarding the electrical speed, absorbed current, flow water and developed flux. A processor-in-the-loop (PIL) test is effectuated as an experimental test of the proposed method. It consists in implementing the generated C code on the STM32F4 discovery board. The obtained results from the embedded board are similar to numerical simulation results.
近年来，光伏水泵系统（PVWPS）效率的提高引起了研究人员的广泛关注，因为它基于更清洁的电能生产运行。本文针对PVWPS应用，开发了一种基于模糊逻辑控制器并结合应用于感应电机（IM）的损耗最小化技术的新方法。所提出的控制通过使感应电机损耗最小化来选择最佳磁通量大小。此外，还引入了变步长扰动观察法。通过降低吸收电流来验证所提出控制的适用性，从而使电机损耗最小化并提高了效率。将所提出的控制策略与无损耗最小化的方法进行了比较。比较结果表明，基于损耗最小化的所提出方法在电气速度、吸收电流、水流和磁通量方面是有效的。进行了处理器在环（PIL）测试作为所提出方法的实验测试。它包括在STM32F4发现板上实现生成的C代码。从嵌入式板获得的结果与数值模拟结果相似。
