摘要
设计了一种基于TMS320F2806无速度传感器的感应电机矢量控制系统,采用转子磁场定向,实现磁链与转矩的解耦控制,利用PI自适应控制原理控制速度和电流,通过磁通估算模块计算磁链和磁通角,然后通过开环速度估计模块估算转子的角速度。实验结果表明,该系统设计简单实用,性能良好。
A new kind of sensorless motor speed control system based on TMS320F2806 is designed.Rotor flux oriented control is adopted to realize flux and torque decoupling.With the principle of PI adaptation control, the speed and the current of the system are controlled. The rotor flux angle is calculated by means of the module of the flux estimator, and then the angle speed is obtained by the module of the open loop speed estimator.It is demonstrated that the method is practical,simple and the performance is good.
