Research on control strategy for single-phase grid-connected inverter based on Proportional Complex Integral Control
A new control approach based on Proportional Complex Integral control for grid-connected current is presented in this paper. The working principle is analyzed, parameter design and implementation method for PCI control are given.this controller is different from traditional PI control, PCI control can introduce the infinite gain at the fundamental frequency,so it not only can eliminate steady-state amplitude and phase errors, but also grid-connected current is not disturbed by Network Voltage at the fundamental frequency completely,but PI control can not eliminate steady-state amplitude and phase errors of grid-connected current, and the function of antiinterference isnt good, Simulation study is made with the tool- boxes of SIMULINK in the MATLAB through theoretical analysis and simulation, effectiveness of PCI control is verified.
