研究目的
To use the Sliding Mode Control (SMC) for the MPPT control of the PV system and compare its effectiveness with the P&O method in terms of implementation complexity, speed of convergence, and accuracy of the monitoring method.
研究成果
The sliding mode controller provides a very short power and response time, is faster and more stable than the P&O method, and correctly regulates the output voltage. The SMC allows the output voltage to catch up to the reference voltage more quickly, demonstrating excellent dynamic performance and robustness despite variations in irradiation.
研究不足
The study focuses on simulation results under varying environmental conditions but does not address physical implementation challenges or real-world environmental variability beyond the simulated scenarios.
1：Experimental Design and Method Selection:
The study employs Sliding Mode Control (SMC) for MPPT control in a PV system, comparing it with the P&O method. The theoretical model includes a photovoltaic panel and a boost converter.
2：Sample Selection and Data Sources:
