In this paper, a novel dual closed-loop repetitive control strategy based on grid current feedback is proposed for single-phase grid-connected inverters with LCL filters. The proportional-integral inner loop is stabilized by using an inherent one-beat delay achieved by digital controller.
In this study, a control strategy combining the three closed-loop control with an iterative-based RMS algorithm is proposed for addressing the voltage drop and slow response problems of single-phase off-grid inverter caused by abrupt load variation under a double closed-loop control.
Secondly, using the pole configuration method, the parameters of the double closed-loop PI can be obtained. Finally, the model is built by SIMULINK. The simulation results verify that the dual-loop control can improve and improve the steady-state performance and dynamic performance of single-phase inverter power supply.
In this paper the design of synchronous frame DQ control based double loop control for single phase inverter in distributed generation system is proposed. For synchronous frame control, the orthogonal signal is generated by second order generalized integrator method.
