摘要
在直接力矩控制系统中，为检测到尽可能低的转速，本文采用Ｔ／Ｍ测速方法，并利用锁相环和ＧＡＬ器件编程技术设计了倍频电路，从而拓宽了测速范围，保证了测速精度，为改善系统的低速性能奠定了良好的基础。
The T/Mmethod is applied to the direct torgue control (DTC)system for measuring the low speed,the freq uency multiplication circuit is designed by means of phaselock loop and GAL device.The range of rotational speed dete cted is expanded and the accuracy is ensured .It lays a foundation for improving the low speed characteristic of DTC system.
