摘要
由于运行中感应电机定子电阻的变化影响了磁通观察，直接转矩控制器在低速时出现运算困难。文中基于所求常规模糊控制表，利用加权插值构造了具有连续输出值的电阻观察器，比较了模糊在线观察结果和工业实测结果，二者吻合良好。仿真表明，该电阻观察器用于直接转矩控制系统中，有效地改善了系统的动静态特性。
The operation of the direct torque controller becomes difficult at low speeds due to the effect of change in stator resistance of induction motor on the flux measurements.Based on the control list obtained by means of conventional fuzzy arithmetic,a new estimator with the continuous values can be constructed by using the interpolating method of weighted sum.The online results from the estimator with the continuous values and that of industrial tests have been found in excellent agreement As this estimator is used in DTC system,the simulated results show that the performance of dynamic and steady states of the motor can be greatly improved
