【Abstract】 The photovoltaic power generation system is susceptible to external conditions, with large output fluctuations and poor immunity. In order to improve the utilization rate of the system, a photovoltaic MPPT control technology combined with fuzzy self-disturbance rejection strategy is proposed to compensate for internal and external disturbances through the extended state observer. Combined with fuzzy control to improve the linear error feedback control law, it can quickly track the voltage and power of the maximum power point of photovoltaic cells, reduce the overshoot, improve the anti-noise performance of the system, and have a good control effect. Finally, a simulation model is built in MATLAB/Simulink to verify the effectiveness and feasibility of the control strategy in improving the response speed and immunity performance of photovoltaic power generation system.更多还原
