The growth of type-2 fuzzy logic system is penetrating electric power system field. especially on electric power system control sub-field in order to simplify the design of power system stabilizer (PSS). Traditionally. the function of conventional PSS is to damp rotor oscillation when a disturbance occurred due to transmission configuration or/and loading changes. http://www.ngetikin.com/great-deal-Soderhamn-Footstool-Cover-great-pick/
