In order to improve the efficiency and precision of maximum power point tracking(MPPT)control,a new method is proposed.Based on original MPPT technology of photovoltaic cells,the fuzzy adaptive proportion-integral-differential(PID)control has less fluctuation and higher stability.The simulation circuit using Simulink is established,and output power curves under constant temperature or constant sunlight are obtained.The superiority of the fuzzy PID control method has been proved by means of the simulation results,and it makes the solar system approach maximum power point quickly and smoothly.
In order to improve the efficiency and precision of maximum power point tracking （MPPT） control, a new method is proposed. Based on original MPPT technology of photovoltaic cells, the fuzzy adaptive proportion-integral-differential （PID） control has less fluctuation and higher stability. The simulation circuit using Simulink is established, and output power curves under constant temperature or constant sunlight are obtained. The superiority of the fuzzy PID control method has been proved by means of the simulation results, and it makes the solar system approach maximum power point quickly and smoothly.
