An adaptive control design is proposed to improve dynamic performances of voltage source converter high voltage direct current (VSC-HVDC) systems. The adaptive controller design for nonlinear characteristics of VSC-HVDC systems. which is based on backstepping method, considers parameters uncertainties. For an original high-order system, the final control laws can be derived step by step through suitable Lyapunov functions. Thus, the design process is not complex. The effectiveness of the proposed adaptive controllers is demonstrated through digital simulation studies on a VSC-HVDC power system, using the PSCAD/EMTDC software package. The simulation results show that the Controllers contribute significantly toward improving the dynamic behavior of the VSC-HVDC system Under a wide range of operating conditions.
