摘　　要：提出了一种采用模糊控制器的异步电机直接转矩控制系统，应用模糊逻辑来确定逆变器的开关状态，把磁链位置、磁链误差和转矩误差作为模糊变量，模糊控制器基于一套模糊规则来选择开关状态，从而有效地提高系统在启动和转矩指令突变时的响应速度。This paper proposes a control system with a fuzzy controller for the implementation of direct torque control.Fuzzy logic is used for choosing the switching state.Flux position,error in flux magnitude and error in torque are used as fuzzy state variables.A fuzzy logic controller can choose the switching states based on a set of fuzzy variables,Which improves the response of the system effectively at the startup and during a change in torque command.

关 键 词：模糊控制 直接转矩控制 模糊规则推理 感应电机
