Dynamics Improvement of 3-Phase Inverter with Output LC-filter by Using Differential Flatness Based Control for Grid Connected Applications

Abstract : This paper proposes a cascade voltage/current control method (vector control) for a three-phase inverter for grid connected applications. The study mainly focuses on the innovative control law based on the flatness properties for a three-phase inverter with output LC filter. Utilizing the flatness principle, we propose simple solutions to the control and stabilization problems. The effectiveness of the proposed controller is validated through experiments on a prototype 1-kVA testbed with a dSPACE 1104 controller platform. Finally, the comparative results for the proposed scheme and the conventional linear control (proportionalintegral control) scheme are presented to demonstrate that the proposed algorithm achieves an excellent performance such as fast transient response.
