Adaptive Control of a Three-Phase Grid-Connected Inverter with Near Deadbeat Response
Grid connected inverters constitute the most important part of any modern day micro-grid. However, for the optimal usage of the resources, it becomes a necessity to track the dynamic changes in the plant parameters. In this paper, a parameter estimation architecture is employed in a synchronous frame of reference and the controller parameters are updated online. To verify the performance of the control come estimation architecture, a deadbeat control is implemented on a three phase grid connected inverter with RL filter. The controller parameter gains are adjusted based on the parameter estimated. Verification of the proposed methodology is carried out via simulation based on MATLAB/Simulink and PLECS domain along with experimental verification on a reduced scale laboratory prototype.
