【摘要】 研究了异步电动机传统的以模型为基础的无速度传感器磁场定向控制方法,为了提高异步电机无速度传感器矢量控制的控制性能,文章提出了一种交流感应电机数学模型的电机转速辨识方法,并将其与矢量控制结合起来,组成了一种基于DSP 56F8346的无速度传感器矢量控制系统。具体介绍了其结构原理及其软件实现方法,并且通过实验验证了所提出方法的有效性。更多还原

【Abstract】 A classical model-based speed-sensorless field-oriented control method for induction(machine) is considered.The paper presents a new method of induction motor speed identification which can improve the performance of the speed sensorless vector control of induction motor.We combine this method with the vector control to form a Field Oriented Control system of speed sensorless based on DSP 56F8346.Its structure and software design are analyzed(detailedly.) The validity of the proposed method is also verified by experiments.更多还原
