太阳能光伏组件是非稳定电源，为有效利用太阳能，必须对其进行最大功率点跟踪（MPPT）。论文分析了光伏发电 MPPT 原理，提出一种基于占空比扰动的 MPPT 控制方法，在 Matlab 中建立扰动观察法和增量电导法仿真模型，仿真结果显示两者均能实现最大功率点跟踪，增量电导法性能要明显优于扰动观察法，但其硬件要求高。研究为光伏发电 MPPT 算法选择提供了参考，当系统精度要求高，硬件能够满足控制要求，可以选择增量电导法，否则应考虑扰动观察法。

Because of solar cells were non-stabilized power,in order to effectively use of solar energy,it need for maximum power point tracking (MPPT). In this paper,the principle of photovoltaic generation MPPT analyzed,and a MPPT control method based on the duty cycle disturbances was proposed. Perturbation and observation(P&O)and incremental conductance(INC)simulation circuit were built in Matlab. Simulation results show that both can achieve maximum power point tracking,INC performance to be better than the P&O. When high accuracy requirements of the system hardware to meet the control requirements,you can select INC,otherwise it should be considered the P&O.
