Abstract
Photovoltaic (PV) systems are increasingly significant contributors to global energy supply, currently accounting for 4% of total needs. However, extracting maximum power from these systems presents a complex challenge due to the nonlinear nature of their electrical characteristics. Factors like temperature fluctuations and varying irradiance levels can significantly impact power output. This work contributes a novel design, testing, and validation methodology for robust Maximum Power Point Tracking (MPPT) control in PV systems. The methodology leverages two newly developed artificial intelligence (AI)-based nonlinear control strategies, Adaptive Neuro-Fuzzy Inference System based on Terminal Sliding Mode Control (ANFIS-TSMC), and Backstepping combined with ANFIS (ANFIS-BS). A validated Model-Based Design (MBD) approach and a two-stage testing sequence provide a comprehensive framework for developing and verifying embedded software for MPPT algorithms. Evaluation results demonstrate the proposed system’s ability to control reference power precisely under diverse atmospheric conditions. Successful integration with a 32-bit ARM microcontroller also paves the way for real-world implementation. The embedded software consistently exhibited high compliance and performance in meeting MPPT requirements across various test scenarios.
