Improved discretization-based decoupled feedback control for series connected converter of SCC

The active superconducting current controller (SCC) adopts the principle of series voltage compensation, which can be utilized to limit the fault current effectively during fault conditions. This paper presents an improved discretization-based decoupled feedback control for series connected converter of SCC. To improve the system dynamics of discretization-based decoupled feedback control, the effect of the control time delay is considered. Furthermore, a linear state feedback loop which considering the output error vectors is added to the control system to achieve the feature of deadbeat. MATLAB simulation is performed to evaluate the performance of the proposed control.
