Most MPPT algorithms are implemented based on voltage sampling, and an algorithm which combines current sampling with a dual control loop for sliding mode control was obtained in [8]. model to simulate the behavior of a photovoltaic cell. In fuzzy control, the input and output variables of the fuzzy logic controller must be set first [19]. The algorithm can consider tracking both speed and convergence, but the algorithm requires high input and output fuzzy domain parameters, and although the tracking speed is fast, the stability of convergence is poor.
