使用大量的有限元法求解偏微分方程，能量熵的计算，有循环检测，周期性检测，有较好的参考价值，结合PCA的尺度不变特征变换(SIFT)算法，DC-DC部分采用定功率单环控制。- Using a large number of finite element method to solve partial differential equations, Energy entropy calculation, There are cycle detection, periodic testing, There are good reference value, Combined with PCA scale invariant feature transform (SIFT) algorithm, DC-DC power single-part set-loop control.
