Abstrakt: This paper investigates the application of a robust non-linear fuzzy sliding mode controller for a high-voltage direct current (HVDC) system based on voltage source converter (VSC). The dynamic analysis of the VSC-HVDC system is formulated using synchronous reference frame, ie. d-q axis model. Fuzzy logic is used to cancel non-linearity and the sliding mode control (SMC) offers invariant stability to modelling uncertainties pertaining due to converter parameter changes, changes in short circuit ratio and fault on converter and inverter buses. Performance of the propose hybrid approach fuzzy logic SMC (FLSMC) is demonstrated through digital simulation studies on a VSC-HVDC two machine power system using MATLAB software package under wide range of operating conditions. The FLSMC provides excellent transient and steady-state performance as well as complete decoupled control of active and reactive power. [ABSTRACT FROM AUTHOR]
