说明：  基于matlab的光伏电池半物理仿真系统的研究 本文从原理上得出简化的光伏电池板数学模型，并分析了在阴影条件下光伏电池板的运行规律，并加以改善，从而得到比较完善的光伏电池板模型。将光伏电池模型在 Matlab/Simulink 中建模并仿真，在 PC机上得出光伏电池 V-I,V-P 特性。最后将 PC 机上 Matlab/Simulink 建立的光伏电池模型通过 AD/DA 板卡于外界真实量交互，为在 Matlab/Simulink 上搭建光伏系统能量提供部分的半物理仿真提出了可行性和合理性。
(Research on Photovoltaic Battery Semi-Physical Simulation System Based on Matlab In this paper, a simplified mathematical model of photovoltaic panels is derived in principle, and the operating rules of photovoltaic panels under shadow conditions are analyzed and improved to obtain a more complete photovoltaic panel model. The photovoltaic cell model was modeled and simulated in Matlab/Simulink, and the PV cell V-I, V-P characteristics were obtained on the PC. Finally, the photovoltaic cell model established by Matlab/Simulink on the PC is interacted with the actual amount through the AD/DA board, providing feasibility and rationality for the semi-physical simulation of building photovoltaic system energy on Matlab/Simulink.)
