摘要
Abstract
Based on the dynamic mathematical model of induction motor direct torque control, the mutual model reference adaptive system (MRAS) method for parameter identification was proposed to implement the rotor speed and stator resistance online identification by changing the roles of reference model and adjustable model used in the mutual MRAS scheme. Computer simulations and experimental results show that the method can obtain high-precision speed identification and solve the problems of dynamic and static performance of the system under the influence of stator resistance variation. The torque ripple of DTC at low speed is also improved.关键词
