Partition control method applied to solar cell array simulator

The invention relates to a partition control method applied to a solar cell array simulator. The invention relates to the technical field of control for simulating output characteristics of a solar cell array. The method comprises the following steps: calculating a peak voltage Ump and a peak current Imp of an I-V curve stored in a data table; measuring the output voltage and the output current of the voltage-controlled current source for N times and taking an arithmetic mean value to obtain voltage U and current I; judging the state of the flag bit F and the size of the voltage U, and controlling by adopting a midpoint look-up table comparison control method or a UI look-up table method; and the controller outputs a control voltage according to the current value obtained by the control method, controls the voltage-controlled current source to simulate the output characteristics of the solar cell array, and performs partition control. Through the control loop, the voltage-controlled current source can output
