狼群算法寻优，基于MATLAB采用智能控制算算法寻求最优解(This work proposes a new meta-heuristic called Grey Wolf Optimizer (GWO) inspired by grey wolves (Canis lupus). The GWO algorithm mimics the leadership hierarchy and hunting mechanism of grey wolves in nature.)

两电平H桥整流电路，电压闭环SPWM调制，含功率计算模块。(Two level H bridge rectifier circuit, voltage closed loop SPWM modulation, and power calculation module)

雅克比迭代法就是众多迭代法中比较早且较简单的一种，其命名也是为纪念普鲁士著名数学家雅可比。雅克比迭代法的计算公式简单，每迭代一次只需计算一次矩阵和向量的乘法，且计算过程中原始矩阵A始终不变，比较容易并行计算。(The jacobian iteration method is one of the earlier and simpler iteration methods, which is also named in honor of the famous Prussian mathematician jacoby. The calculation formula of jacobian iterative method is simple. Every iteration only needs to calculate the matrix and vector multiplication once, and the original matrix A is always the same in the calculation process, which is easier to calculate in parallel.)

说明：  能够对一段数据进行med处理，对一段信号降噪进行降噪处理，减少噪声对信号的影响，使信号在之后的处理中其故障特征频率能更好地表现出来。(It can process a section of data with MED, reduce the noise of a section of signal, reduce the impact of noise on the signal, and make the fault characteristic frequency of the signal better show in the subsequent processing.)
