例句與造句

1. How to improve the accuracy of flux observer is very important in high - performance motor system , especially at low - speed or zero - speed situation . high - frequency signal injection is believed the efficient method to solve these difficuilties
   高頻信號注入來實現(xiàn)極低速甚至零速情況下磁鏈位置的觀測是目前該領域的熱點研究內容，本文采用的是d - q軸阻抗差異法。
2. The principle of the fault distance measurement for small current grounding system by injecting dual frequency signal are discussed from many aspects such as the method and the characteristic of the signal , the test of the signal , the method of the line select , the algorithm of the fault distance measurement , and the method of the fault location , etc . the task adopts this kind of principle , in which the signal injection is completed by the coupling between the power source and the pt
   在詳細地說明以上三種測距算法的基本原理后，分析各種算法的優(yōu)缺點，從注入信號的方法、特征，注入信號的檢測，接地選線的方法，故障測距的算法，及故障定位的方法等多個方面，論述了本課題采用的應用于小電流接地系統(tǒng)的雙頻信號注入式測距原理。其中，信號的注入由功率源通過電壓互感器( pt )耦合來完成。
