摘要
为了克服机械式传感器给永磁同步电机调速系统带来的缺陷,深入研究了永磁同步电机脉振高频电压信号注入法的原理,采用PI控制算法对转子位置进行无偏估计,实现了永磁同步电机无传感器的矢量控制。在以TMS320LF2407A为控制核心的实验平台上进行了验证,结果表明脉振高频电压信号注入法切实可行,能够实现电机的正反转、加载等实验,具有良好的调速性能指标。
In order to overcome the defects caused by mechanical sensor to the permanent magnet synchro- nous motor speed regulating system, in-depth study of the principle of permanent magnet synchronous motor fluctuating high-frequency voltage signal injection method, used PI control algorithm to unbiased estimate the rotor position, and realised of sensorless permanent magnet synchronous motor vector Control. On the ex- periment platform with TMS320LF2407A as the control core was verified, the results show that the fluctua- ting high frequency voltage signal injection method was feasible and could achieve motor and reverse, load experiment, such as good speed regulation performance metrics
