完成两个混合正弦信号的分离，分离是从频域的角度(Complete separation of the two mixed sine signal, separating from the perspective of frequency domain)

powell法求极值，根据课程老师布置的作业，其中包括黄金分割法，一维进退法(powell method)

对电网不平衡情况下的三相PWM整流器进行了详细的建模分析，并在此基础上研究了两种不平衡控制策略。其一是抑制网侧负序电流的控制策略，主要控制三相PWM整流器交流电流对称正弦化控制。其二是抑制直流电压谐波分量的控制策略，主要控制三相PWM整流器从电网吸收平衡的瞬时功率，消除直流电压中的各次谐波分量。(Research on the Control strategy of Three-Phase PWM Rectifiers under Unbalaneed Grid Voltage)
