摘要
针对直接转矩控制系统在低速时对电机参数的依赖性,提出一种基于模型参考自适应的定子磁链观测器,该观测器在观测定子磁链的同时也辨识了电机参数,笋观测出电机转速。在此基础上构建了无速度传感器的直接转矩控制系统仿真模型,结果验证了该方法的正确性。
For the dependence on the motor parameter for the DTC control of induction motor, a stator flux estimator based on MRAS is designed. This estimator not only can observe the stator flux, but also can observe speed and parameter. According to this model, a emulation model of speed-sensorless DTC control system is constructed. Results of simulation show that this method is correct.
