| 摘 要： | 针对小功率单相并网逆变器传统网压前馈的PI(比例积分)控制器在跟踪正弦电流指令时存在稳态误差和抗干扰能力差等方面缺陷,文中给出了一种PR(Proportional-resonant比例谐振)控制器,并在稳定性、稳态误差和抗干扰性能上比较了PI和PR两种控制器.最后,搭建了仿真和实验平台,对理论分析结果进行验证.结果表明PR控制器在单相并网电流控制更具有优越性.

| Abstract: | Due to the well known drawbacks of PI controller: steady-state magnitude and phase error and limited disturbance rejection capability,one novel current control scheme named PR(Proportional-Resonant) is introduced.Some comparison results between PI and PR controller among stability,steady-state error and anti-disturbance are given.By using PR controller,the single phase gird connected inverter achieves both zero-steady-state error and the good disturbance rejection capability.Some simulation results with Sim... |
