High voltage direct current (HVDC) transmission system is very suitable for the high power long distance transmission and plays an important role in the West to East Power Transmission Project. The security and stability of the HVDC system is ensured by the well influence of its controller. However,the HVDC system is a strongly nonlinear,uncertain system. The study on improving the robustness of the controller of HVDC system is important.
