    Study Notes

    Thesis Goals and Background

    • This thesis will examine the use of P&O (Perturb and Observe) and ANFIS (Adaptive Neuro-Fuzzy Inference System) MPPT controllers in solar photovoltaic (PV) powered water pumping systems.
    • The focus is on the application of these technologies in the Amude region of Oromia, Ethiopia.
    • The context is the need for reliable water sources in rural areas where grid electricity is unavailable.
    • The advantages of solar PV water pumping systems include their environmental friendliness, portability, and low maintenance needs.
    • The disadvantages of traditional diesel-powered water pumping systems are their dependence on fossil fuels, high operating costs, and environmental impact.

    ANFIS Controller

    • ANFIS combines the learning capabilities of neural networks with the reasoning abilities of fuzzy logic.
    • ANFIS is suited for complex systems and can be classified based on its architecture, learning mechanism, and rule-based system.
    • ANFIS can help improve MPPT controller performance in solar PV water pumping systems by optimizing power output.
    • ANFIS MPPT systems can offer less fluctuation around the maximum power point (MPP), faster tracking speed, and lower computation time.
    • Challenges for ANFIS include the need for accurate training data and tuning of the model.

    Modeling and Methodology

    • The methodology will draw on data collection, system design, and modeling of PV cells, DC-DC converters, and ANFIS-based P&O MPPT systems.
    • The specific steps include identifying needs, reviewing existing literature, gathering data, and developing models of the PV, DC-DC converter, and the MPPT system.
