Abstract:

This paper proposes a current controller for grid tied Voltage Source Inverter (VSI) via a LCL filter using discrete-time Sliding Mode Control (SMC) in a multi-loop framework. The inner loop is implemented by the SMC with reference generated by an outer controller for the VSI side current. The tracking of the current entering the distribution network is ensured by a outer controller with a derivative + ressonant structure (for compensation and disturbance rejection with reference tracking). Simulation and experimental results are presented to validate the good performance of the proposed control strategy.
