Disturbance Observer-Based Adaptive Current Control With Self-Learning Ability to Improve the Grid-Injected Current for <inline-formula> <tex-math notation="LaTeX">$LCL$ </tex-math></inline-formula>-Filtered Grid-Connected Inverter

During the design of the conventional current controller for a grid-connected inverter with <italic>LCL</italic> filter, the parameter mismatches and disturbances are generally neglected, which may seriously affect the control performance, even result in instability. In order to improve...
