基于DSP的无速度传感器控制系统研究

Study of speed-sensorless direct torque control system based on DSP

为了实现快速准确地观测电机转速,在直接转矩控制系统的基础上,采用了基于电机转子磁链的MRAS速度辨识方法对系统进行速度估计,并通过DSP实现无速度传感器的直接转矩控制。利用Matlab对系统进行仿真分析,仿真结果表明,该方案的设计方法正确可行。

In order to accurately observe the motor speed, this article based on the motor rotor flux of MRAS speed identification method for system speed estimation in DTC, and through DSP to achieve DTC without speed sensor. Using MATLAB to simulate system analysis, the simulation results show that the design method is correct and feasible.
