粒子群优化算法的一个寻优案例,测试函数含有多个局部极值，尝试用PSO算法寻找全局极值(a case of Particle Swarm Optimization algorithm.)

说明：  二相相移键控（BPSK）是用二进制基带信号（0、1）对载波进行二相调制。BPSK是最简单的PSK形式，相移大小为 180°，又可称为2-PSK。在群点聚集的地方，其实都不是非常有关系，在该图像中，群点分布在水平轴上的0°和180°上。由于BPSK使用严重的失真致使解调器作出错误的判断，所以该调制方式是所有PSK中最强的。但它只能以1bit/symbol调制而不适合高数据率应用情况。 (bpsk modulation)

考虑到不平衡电网条件下，传统锁相环的局限性，这里比较了几种基于正负序分离的锁相环着重基于陷波器的提取方式(Taking into account the unbalanced grid conditions, the limitations of the traditional PLL, where positive and negative sequence based on comparison of several separate PLL trap of focusing on ways to extract)
