Two control schemes＇ research of asynchronous motor＇s speed control system

无速度传感器交流调速技术是相对于传统有速度传感器而言的系统控制精度与性价比更高的技术，本文针对矢量控制和直接转矩控制两种控制方法分别提出相应的速度自适应辨识方案，并且利用SIMULINK进行仿真，结果说明本文提出的速度自适应方案是可行的。

Non-speed sensor A C variable speed is accuracy, more cost-effective technology.In this paper proposed for vector control and direct torque control, indicate programs proposed in this paper are feasible related to the traditional speed sensor in terms of there are two programs of speed adaptive will be and the programs are sinmlated by SIMULINK, the result
