通过介绍空间电压矢量脉宽调制(SVPWM)控制策略在无速度传感器矢量控制系统中的实现,在此基础上给出了基于DSP的全数字化调速系统,并分别建立了改进的电压型转子磁链观测模型和PI自适应速度估算模型。实验结果表明:所采用的控制方法正确可行,控制系统具有良好的性能。

This paper presents a SVPWM control method in speed sensorless vector control system. According to that a digital motor drive system based on TMS320F2407 is given. Also the improved rotor flux estimation model and the adaptive speed estimation model are built separately. The experiment results with the induction motor prove this control method can achieve better performance.
