摘　　要：分析了现有光伏电池MPPT控制方法的优点和不足,提出了一种基于自整定模糊PID算法的光伏电池MPPT控制系统.在Matlab/Simulink环境下建立了光伏电池模型和基于自整定模糊PID算法的MPPT控制系统.仿真结果表明:该系统跟踪速度快、静态误差小;当外界环境变化时,能够迅速准确地作出响应,找到最大功率点;系统在稳定时基本消除了震荡现象,具有良好的动态和静态特性.自整定模糊PID控制具有较强的自适应能力和鲁棒性.The photovoltaic cell MPPT control method in the strengths and weaknesses is analysed. Based on fuzzy self-tuning PID algorithm of the photovoltaic cell MPPT control system is proposed. In Matlab/Simu- link environment model of photovoltaic ceils based on self-tuning fuzzy PID algorithm of MPPT control system is established. Simulation results show that： This method has tracking speed, the static error is small, when the external environment changes, responds quickly and accurately finds the MPP, especially when the system is stable and substantially the vibration phenomenon is eliminated, has a good dynamic and static characteristics. Self-tuning fuzzy PID control has a strong adaptive ability and robustness.
