Study on Permanent Magnet Synchronous Motor's Speed Control System Using Neural Network

为改进传统PID控制的永磁同步电动机(PMSM)调速系统性能,设计了神经网络速度控制器并对其构成的矢量控制系统进行了仿真分析。结果表明,当电机参数改变或受到外部扰动时,该系统具有更好的动态性能。

In order＇ to improve the performance of the Permanent Magnet Synchronous Motor＇s speed control system, an neural network is designed and simulation research is done in connection with the vector control system based on designed controller. The results of simulation show that the system has high dynamic performance under the occurrence of parameter variations and external disturbance.
