I was looking for anything abnormal, such as devices in a Defined state or permanent hardware errors in the error log. 我寻找任何异常情况,比如处于Defined状态的设备或错误日志中持久的硬件错误。
In MSS, the result of a permanent reading error during an attempt to read a particular stripe of a data cartridge. 在海量存储系统(SS),在试图读数据盒式磁带的某一特定区段时产生的永久性读错误。
This is a permanent error. 这是一个永久错误。
Referring to a PMSM ( permanent magnet synchronous motor) driving system with only two low-cost hall sensors, We analyze the position-measuring error in one pseudo-sensorless scheme, and offer methods of error compensation. 结合一套只采用2个低成本霍尔传感器的永磁同步电动机驱动系统,文中分析了准无位置传感器方案中的位置检测误差,给出了误差的补偿方法。
The proposed method only requires the flux linkage of the permanent magnet and is insensitive to parameter estimation error and variation. 这种方法只需要确定永磁磁链。且对参数估算的误差及变化不敏感。
In addition, the power equation, used the rotor opposite angle ( relative other rotors), loads replaced with the permanent impedance parts, based on linear network superimposition, therefore more complex and big error with the reality system. 此外,功率方程由于采用了转子相对角(相对其它转子),将负荷用恒阻抗元件代替,基于线性网络叠加而得,故较为复杂且与实际系统误差较大。
Based on the mathematical model of the permanent magnet synchronous motor, the sliding surface form according to the error between measured current and observational current, using observed back EMF to calculate estimated speed/ position. 基于永磁同步电机的数学模型,根据实测电流和观测电流之间的误差构成滑模面,应用观测得到的反电动势计算出估计的转速/位置。
Ensuring that the permanent magnet fits the application required and the permanent magnet coupling works in permissible range, the error between test of temperature rise and calculation value was less, which verified the accuracy of the calculation method of temperature rise. 然后通过温升试验,对比得到试验值与计算值误差较小,验证了温升计算方法的准确性,并保证永磁体符合应用要求,且确保永磁耦合器在可允许的范围内工作。
