EAST fast-control power supply output current prediction method based on improved gray GM (1, 1) model prediction

The invention discloses an EAST fast-control power supply output current prediction method based on improved gray GM (1, 1) model prediction, relates to the technical field of EAST fast-control powersupplies, and solves the problem of poor control precision of EAST fast-control power supply output current. the EAST fast-control power supply output current prediction method comprises the steps of:dividing an original sequence into an ascending stage sequence and a descending stage sequence according to the monotonicity of the original sequence of an output current of an EAST fast control power supply; and establishing a non-equidistant gray GM (1, 1) prediction model for the ascending stage sequence, establishing an equidistant gray GM (1, 1) prediction model for the descending stage sequence, and calculating a prediction value of the output current of the EAST rapid control power supply according to the prediction models, thereby realizing precise and rapid control of the output current of the EAST rapid cont
