    • Disclosed is a method and apparatus for detecting an excitation position of an SRM by comparison of detected currents. The method includes detecting a current by applying a first test voltage to each phase of the SRM, detecting a current by applying a second test voltage to each phase, determining an operation state of the SRM based on a deviation between the currents detected in any one of the phases, determining the operation state of the SRM as a rotation state if the deviation value exceeds a predetermined value, and applying a third test voltage to a phase excited just prior to a current excited phase to detect the current and turning on a phase to be next excited if the detected current value is more than a first reference value, and turning off the phase excited just prior to the presently excited phase if the detected current value is more than a second reference value. The phase excitation position is accurately detected according to the rotating speed without using a position sensor.
    • 公开了一种通过比较检测电流来检测SRM的激励位置的方法和装置。 该方法包括通过对SRM的每个相位施加第一测试电压来检测电流,通过对每个相位施加第二测试电压来检测电流,基于在任何一个中检测到的电流之间的偏差来确定SRM的操作状态 如果所述偏差值超过预定值,则将所述SRM的运行状态确定为旋转状态,以及将第三测试电压施加到刚好在当前激励相位之前激发的相位,以检测所述电流并打开相位 如果检测到的电流值大于第一参考值,则接下来激发,并且如果检测到的电流值大于第二参考值,则关闭刚好在当前激励阶段之前激发的相位。 在不使用位置传感器的情况下,根据转速精确地检测相位激励位置。

    • Disclosed herein is a torque control method for a high-speed Switched Reluctance Motor (SRM), which controls a torque in the high-speed operation of a 2-phase SRM. In the torque control method for a high-speed SRM, a positive torque (T*mA) of an active phase (A phase) of the two phases of the SRM is compensated for based on a negative torque attributable to an inactive phase (B phase) of two phases during a compensation control enable interval (ENA) ranging from a time point at which the active phase (A phase) is turned on to a time point at which tail current of the inactive phase (B phase) remains. Accordingly, the present invention can remarkably reduce a torque ripple occurring in high-speed operation mode in consideration of the influence of a negative torque attributable to tail current.
    • 这里公开了用于控制两相SRM的高速运转中的转矩的高速开关磁阻电动机(SRM)的转矩控制方法。 在高速SRM的转矩控制方法中,SRM的两相的有效相(A相)的正转矩(T * mA)根据归因于无效相(B 在从有源相位(A相)接通的时间点到停止阶段(B相)的尾部电流保持的时间点的补偿控制使能间隔(ENA)期间的两相的相位。 因此,考虑到归因于尾部电流的负转矩的影响,本发明能够显着地降低在高速运转模式中发生的转矩脉动。

    • Disclosed is a method for controlling activation/deactivation of two kinds of operation modes of an MMMB mobile terminal during handover between different types of systems. To control the activation/deactivation, a system controller instructs the mobile terminal to activate/deactivate the operation modes or provides activation/deactivation conditions to the mobile terminal. In particular, when the mobile terminal in communication is situated in a border cell neighboring a target system, the mobile terminal activates target system-related modules and then performs handover into the target system according to predetermined conditions after the passage of a predetermined time period. Such a handover method minimizes time required for performing handover, prevents deterioration of call quality during the handover, and saves power consumption of the mobile terminal.
    • 公开了一种在不同类型的系统之间切换期间控制MMMB移动终端的两种操作模式的激活/去激活的方法。 为了控制激活/去激活,系统控制器指示移动终端激活/去激活操作模式或向移动终端提供激活/去激活条件。 特别地,当通信中的移动终端位于与目标系统相邻的边界小区中时,移动终端激活目标系统相关模块,然后根据预定时间段之后的预定条件执行到目标系统的切换。 这种切换方法使得执行切换所需的时间最小化,防止切换期间的呼叫质量恶化,并且节省了移动终端的功耗。
