%0 Journal Article %T Efficiency of VSC-HVDC System With Various Fuzzy Models %A Mrs. Sonali R dasgupta %A Dr.(Mrs.) Gayatri Agnihotri %J International Journal of Engineering Science and Technology %D 2011 %I Engg Journals Publication %X This paper suggests a Shrinking Span Membership function to be utilized in very fact changing system just like VSC- HVDC system. In this particular work Mamdani controller as well as the Takagi-Sugeno controller are compared with exact same input function(Shrinking Span Membership) in simulation as well as on prototype hardware. Simulation result justify the. Takagi-Sugeno Controller gives better dynamic response then the Mamdani controller %K Fuzzy Controller %K Pulse width modulation %K HVDC transmission %U http://www.ijest.info/docs/IJEST11-03-05-100.pdf
