Maximum power point tracking (MPPT) is necessary to achieve an optimal exploitation of photovoltaic (PV) system. This paper presents a novel voltage-oriented MPPT (VO-MPPT) method, where the conventional perturb and observe (P&O) algorithm is combined with the proposed external voltage control based on an adaptive integral derivative sliding mode (AIDSM). It is designed with new sliding surface, in addition, the derivative and integral terms are chosen to eliminate the overshoot during fast changes in solar irradiation and to minimize the steady-state fluctuation. Furthermore, an adaptation mechanism is joined to adjust the controller gains under each irradiation level. The proposed MPPT is tested and compared with the most widely used MPPT methods by simulations using MATLAB/Simulink and real time hardware in the loop (HIL) implementation. The results obtained with the proposed MPPT show excellent dynamic performance under fast irradiation changes.
最大功率点跟踪（MPPT）对于实现最佳的光伏（PV）系统利用是必要的。本文提出了一种新颖的电压定向 MPPT（VO-MPPT）方法，其中传统的扰动观测法（P&O）算法与基于自适应积分微分滑模的外部电压控制（AIDSM）相结合。该方法设计了新的滑动面，此外，选择导数和积分项以消除在太阳辐照度快速变化期间的过冲，并最小化稳态波动。此外，加入了一种自适应机制，以根据每个辐照度水平调整控制器增益。使用 MATLAB/Simulink 进行仿真，并通过实时硬件在环（HIL）实现与最广泛使用的 MPPT 方法进行了测试和比较。所提出的 MPPT 在快速辐照度变化下表现出出色的动态性能。
