State Feedback Current Control of the Three-Phase Grid Connected Power Inverter for the Regenerative Loads

Article Preview

Abstract:

Grid-connected power converters are controlled by the current loop, the voltage being delivered by the grid. The proposed state feedback current control has three components: the state feedback, the forcing component to achieve the desired state x1 and the compensating feed forward of the perturbation. Moreover, the control of the power converter, through the external DC-link voltage loop, and internal current loop, assures zero steady state error, and power quality performances. In order to prove the quality of the proposed control, a regenerative load has been used, and the corresponding simulation results are provided.
