Özet
In this paper, we propose improved passivity based control (PBC) strategy for grid connected voltage source converter (VSC). In order to provide global asymptotical stability of the closed loop control system in the sense of Lyapunov approach, VSC is modelled within port-Hamiltonian framework. Classical PBC techniques are insufficient to achieve zero steady state tracking error. To eliminate this errors caused by constant disturbances, integrator is inserted into to the proposed PBC. Furthermore, designed adaptive observer allows sensorless operation for the proposed method. Simulation results are presented to validate the proposed controller. © 2019 IEEE.
