中文摘要：
为了解决传统的比例-积分（PI）控制器由于自身缺陷引起的电压、电流谐波问题,提出了两相同步旋转坐标系下基于比例-积分-谐振（PIR）控制器的电压、电流双闭环逆变器控制策略;同时引入了简化三电平空间矢量脉宽调制（SVPWM）算法,并在此基础上提出相电压重构方法.仿真实验表明,上述控制策略对指定次谐波具有良好的抑制效果,采用该策略的逆变器具有良好的输出特性,进而验证了该控制策略对并网系统的有效性.
英文摘要：
In order to overcome the harmonics problems of voltage and current because of self-defect of proportionalintegral （PI）controller,a voltage-current close loop inverter control strategy based on proportion-integration-resonant （PIR）control method is proposed.Furthermore,a method of phase voltage reconstitution is proposed based on simplified 3-level SVPWM algorithm.The simulation result demonstrates that this control strategy can decrease the selected low order harmonics better.The inverter has superior output characteristic,and the correctness and feasibility of the control strategy is verified.
