PURPOSE: A yaw control system of aerogenerator and a control method thereof are provided to include at least two controllers that control at least two electric driving motors, thereby stably operating the yaw system by the remaining controllers although any one of controllers malfunctions. CONSTITUTION: A yaw control system of aerogenerator includes at least two controlling units (210,220) and a malfunction determining control unit (240). The at least two controlling units include at least two driving motors and a controller that controls the at least two driving motors, respectively. The malfunction determining control unit detects the malfunction that is generated in the at least two control units, determines the type of malfunction, and then transmits the signal of operability in a case where the determined type of malfunction is the type of malfunction capable of operating. Controllers (211,221) that constitute the respective at least two control units are electrically connected to the respective driving motors that constitutes the respective control units, and the controller of control unit that is transferred with the transmitted signal of operability controls the respective driving motors that constitutes the control units that are not transferred with the transmitted signal of operability.
