| 摘 要： | 在建立异步电机直接转矩控制动态数学模型的基础上,提出了交互式模型参考自适应参数辨识方法,通过参考模型和可调模型互换,实现了带定子电阻参数辨识的转速观测.仿真和实验结果表明,该方案不仅实现了转速的高精度辨识,而且能较好地解决定子电阻变化对系统动静态性能的影响,改善了异步电机无速度传感器直接转矩控制低速转矩脉动.

| 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 performa... |
