摘  要：
光伏电池由于其非线性功率输出特性,需要实时变更光伏系统的输出特性进行最大功率点追踪(MPPT)。传统基于Buck或Boost拓扑的PID恒压控制法的MPPT技术,具有精度差、调节时间长、灵活性差等不足,提出了一种采用仿人智能控制算法(HSIC)进行恒压控制,并在电路拓扑上采用Buck-Boost拓扑电路代替传统的Buck或Boost电路,最后在MATLAB/SIMULINK下进行建模仿真。实验结果表明,该控制方法灵活性高,控制速度和精度等动稳态性能优于一般的PID控制方法,证明了该控制方法的有效性。

摘  要：
Photovoltaic cells because of its nonlinear power output characteristics, need to change output characteristic of maximum power point tracking(MPPT) in real-time system. Traditional MPPT technology of PID constant voltage control method based on Buck and the Boost topology is lack of accuracy, long adjusting time and poor flexibility. In this paper, a new method of constant voltage control based on the algorithm of human-simulated intelligent control(HSIC) is put forward, and the traditional Buck or Boost circuit is replaced by the Buck- Boost topology circuit on the circuit topology and this method is established and simulated under MATLAB / Simulink. The experimental results show that the control method is of high flexibility,the dynamic and static performance such as controlling speed and accuracy is better than general PID control method, which proves the effectiveness of the proposed control method.
