针对光伏电池阵列最大功率点跟踪速度和跟踪精度难以同时兼顾的问题，提出了一种基于双侧扰动变步长MPPT控制算法，即双向变步长扰动观察法，并与电导增量法、传统扰动观察法进行仿真对比分析。仿真结果表明，该算法可以快速跟踪到最大功率点，精确度提高了15 ms，具有较好的时效性。

For photovoltaic battery array, the maximum power point tracking speed and tracking accuracy is difficult to taking into account simultaneously, proposes a MPPT control algorithm based on bilateral disturbance variable step length, namely two-way variable step perturbation and observation method. Simulates and comparative analyzes the algorithm with the incremental conductance method and the traditional perturbation and observation method. The results show that the algorithm can quickly track the maximum power point and improve the accuracy of 15ms, and it has better timeliness.
