间接位置 meaning in English

indirect position

In research of controlling system about the switched reluctance motor system ( srd ) , there are two prominent problems , one is that it is difficult to set up accurate mathematical model of srm due to serious nonlinearity caused by double - salient structure , the other is that the previous schemes of srd are always equipped with rotor position sensor , which determines the system ' s high speed performance , reliability and cost . as a result , how to detect the position of non - position sensor rotor has become one major direction in the study o f srd
其中较为突出的问题是： 1 )由于sr电机的双凸极结构，电机模型具有严重的非线性，使得建立sr电机的数学模型非常困难； 2 )转子位置传感器的存在影响了电机控制系统的高速性能、可靠性和成本，所以研究无位置传感器转子位置检测技术(或间接位置检测技术)是开关磁阻电机系统( srd )系统研究的重要课题之一。
