摘要
针对传统状态反馈控制无法消除并网交流电流稳态误差的缺点,提出一种带积分控制的三相并网逆变器状态反馈技术,给出了控制器参数整定方法,并采用TMS320F2812型DSP实现系统的数字化控制。仿真和实验验证了大功率三相并网逆变器采用该方案既消除了稳态误差,又具有良好的稳、动态性能。
State feedback method is conventionally regarded as an unsatisfactory solution for AC grid-connected invert- er systems because it cannot eliminate steady-state amplitude and phase errors.This paper proposes a novel inverter control system based on state feedback with integral control, and a step by step parameters design procedure is given also.The control system is digitally implemented with TMS320F2812 DSP.Simulation and experimental results verify that the scheme eliminates steady-state amplitude and phase errors and provides nice dynamic and static characteristics.
