摘要
提出了一种基于降维观测器的模型参考自适应(MRAS)速度辨识的方法,无需复杂的旋转坐标变换,实现简单。利用Matlab/Simulink建立了无速度传感器直接转矩控制系统仿真模型,仿真结果表明该方法具有较好的速度辨识精度且鲁棒性强,控制系统具有良好的动静态性能。
A model reference adaptive speed identification algorithm based on reduced order model was presented. It didn＇ t need complex rotational coordinates conversion and it was simple. The simulation model of speed sensorless direct torque control system using Matlab/Simulink was built. The simulation results showed that the means had higher speed identification precision and better robustness and the whole control system also had favorable dynamic and static performances.
