Free QuoteIn 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.
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.
By establishing the mathematical model of the single-phase inverter, the current inner loop control can obtain rapid dynamic performance, and the voltage outer loop control can improve the steady-state performance of the system. Secondly, using the pole configuration method, the parameters of the double closed-loop PI can be obtained.
The main circuit topology is a single-phase grid-connected inverter with LCL filter. The repetitive dual-loop control method is adopted. The outer loop is controlled by the RC, which makes the grid-connected current ig track the sinusoidal reference iref without a steady-state error.
Abstract: This letter proposes an adaptive Lyapunov-based control strategy for a single-phase uninterruptible power supply inverter with inherent dual control loops. The control law is derived via a proposed Lyapunov function which takes both dual-loop requirements and the global large-signal stability demand into account.
