摘要
根据异步电机矢量控制的基本原理,构建了一个无速度传感器矢量控制系统,给出了系统软件实现流程图以及转速估计的源程序。该系统采用转子磁链观测器,并通过自适应算法实现对转子速度的估计。并且在MATLAB/Simulink下构建了系统的仿真模型,仿真结果表明该系统采用的控制方法正确可行,控制系统具有良好的性能。
The speed sensor-less vector control system is established according to the principle of vector control system for asynchronous motors. The rotor fl ux is observed by the improved rotor flux observer, and the speed of the rotor i s evaluated by the speed adaptive algorithm. In the end the simulation model of the system is established by the MATLAB/Simulink. The simulation results show th at this control method can achieve better performance.
