摘　　要：针对在噪声干扰情况下,光伏阵列最大功率点跟踪(MPPT)可采用递推最小二乘估计削弱量测噪声干扰影响的方法,运用李雅普诺夫稳定性理论,分析了基于递推最小二乘估计的光伏阵列MPPT控制的稳定性,提出了系统的稳定性判据,为在噪声干扰情况下实施稳定性检测和MPPT提供了理论依据。最后搭建了独立光伏系统实验平台,实验结果验证了所提稳定性分析的正确性和有效性。For noise interference situations, a method using recursive least squares estimation methods to weaken the effects of measured noise is proposed.And then using the Lyapunov stability theory to analysis the stability of the recursive least squares estimation of the photovohaic array maximum power point tracking （MPPT） control, and a stability criterion is proposed.This criterion can provide theoretical basis for the implementation of stability detection and the MPPT in the case of noise jamming.Finally,the correctness and effectiveness of the stability analysis are verified by the experimental platform of the system independent photovoltaic system.
