| 摘 要： | 太阳电池最大功率跟踪(MPPT)控制方法有很多。从比较简单的控制方法如:直线近似法、电压反馈法、扰动观察法、增量电导法等发展到具有智能化的控制方法,如:模糊控制、神经网络控制等。每一种MPPT控制策略均具有自身的特点。对扰动观察法进行了分析,同时利用非对称模糊算法对扰动观察法进行了改进,减少了扰动观察法的震荡过程,确保了光伏阵列稳定地工作在最大功率点附近。仿真结果证明,利用非对称模糊算法改进的MPPT,具有良好的适应性。

| Abstract: | Solar maximum power point tracking(MPPT) has a lot of control methods.There are relatively simple control methods,such as linear approximation method,line voltage feedback method,perturbation and observation method,the incremental conductance method.Also,there are the intelligent control methods,such as fuzzy control and neural network control.Each MPPT control strategy has its own characteristics.The perturbation and observation method was analyzed in this paper,which was improved by non-symmetric fuzzy al... |
