摘要
为了实现对异步电机的高性能控制,在直接转矩控制的基础上,结合定子磁场定向和转子磁场定向各自的特点,讨论了速度估计的算法,提出了一种简单、实用的速度估计方法,并通过DSP (TMS320F2812)实现了无速度传感器直接转矩控制。实验结果表明算法正确、方案可行。
In order to enhance the performance of induction motor, based on the direct torque control, combining the characteristics of both state - flux - oriented control and rotor - flux - oriented control, the scheme of speed estimation for motor in detail is discussed. A simple and applicable speed estimation method of AC motor is put forward. The speed sensorless direct torque control based on DSP （TMS320F2812） for asynchronous motor is implemented. The result shows the theory analysis is right and the scheme is reliable.
