摘要

提出了异步电机直接转矩控制的模糊实现方法。将定子磁链误差、电机电磁转矩误差和磁链角位置作为模糊变量，通过模糊决策选择逆变器电压矢量。仿真结果表明，与传统的直接转矩控制(DTC)相比，该控制减小了转矩的脉动量。它还改善了转矩上升时间和转矩响应在指令转矩突变。

Fuzzy implementation of Direct Torque Control of Induction machine

Fuzzy implementation of direct torque control of induction machine is presented here. Error of stator flux, error of motor electromagnetic torque and position of angle of flux are taken as fuzzy variables, voltage vector of inverter is selected through fuzzy decision. Simulation results shows that ripple content of torque is reduced compared with conventional direct torque control (DTC). It also improves torque rise time and torque response during an abrupt change in command torque.
