Abstract: In order to realize the real-time monitoring requirement of the micro-nano satellite power system, the temperature, output power and battery capacity of the solar cell array are modeled. Considering the attitude change during satellite operation, combined with the satellite in orbit movement, under the background of a certain power supply demand task, the energy change of micro-nano satellite power system is calculated in real time, and the simulation results are studied and analyzed to determine whether the satellite energy can reach the single loop balance. In view of the complex reasons for the change of lithium ion battery capacity, which is difficult to measure directly, fuzzy inference is used to calculate.
Keywords: solar cell array; output power; capacity; simulation; fuzzy inference
