Output Impedance Modified Based Waveform Control for Single Phase Inverter

Article Preview

Abstract:

Repetitive control (RC) has the ability to compensating periodical disturbance and it is an effective way to improve the output waveform of inverter loaded nonlinear load, but the dynamic response is slow. From the perspective of output impedance, state feedback control is used to configurate the pole of the system so that it can modify the ouput impedance characteristic of the system, increase the damp ratio and promote the dynamic performance of the system. The simulation results show that the proposed compound control strategy make the system has advantages of good output waveform and fast dynamic response.
