Method for predicating voltage of solar unmanned aerial vehicle cell panel

The invention provides a method for predicating voltage of a solar unmanned aerial vehicle cell panel. The method for predicating the voltage of the solar unmanned aerial vehicle cell panel comprisesthe following steps of 1, acquiring an operation parameter of the solar cell panel, obtaining a training set and a prediction set according to the operation parameter, and performing normalization processing on operation parameter data of the solar cell panel in a sunny day; 2, building a BP neural network according to the normalized training set; 3, obtaining the initial weight and initial threshold value of the BP neural network through optimization according to an adaptive differential algorithm; 4, using the optimized weight and threshold value as the initial weight and initial threshold value of the BP neural network, and training the BP neural network by means of the training set; and 5, inputting the to-be-predicated data in the predication set into the BP neural network, comparingthe predication value which is output from the BP neural network with an actual value, and evaluating accuracy of a predication result.
