    摘要： The present invention relates to the field of electric drive devices and electric machines, such as electric motors and electric generators for industrial applications and more particularly to a method and an arrangement for controlling vibration of a variable frequency drive controlled electric machine. In the method for controlling vibration of a variable frequency drive (11) controlled electric machine (12), the resonance frequency/frequencies and the stiffness are determined (30) in a ramp up/ ramp down test; amount of damping is determined (40) in an impulse test; a mechanical transfer function is determined (50) in a steady drive test; a vibration control model is determined (60) utilizing said resonance frequency/frequencies, said stiffness, said amount of damping and said mechanical transfer function; and vibration is controlled (70) utilizing said vibration control model.

    摘要： An electric motor controller controls an electric motor including a rotor and a stator that faces the rotor. A current drive unit drives the motor based on an axis current value in a rotating coordinate system that rotates in accordance with a control angle that is a rotational angle used in a control. An addition angle calculation unit calculates an addition angle that is added to the control angle. A control angle calculation unit obtains a current value of the control angle by adding the addition angle to an immediately preceding value of the control angle in each predetermined calculation cycle. A torque detection unit detects a torque that is applied to a motor driven member except a motor torque. A changing unit changes a parameter for controlling the electric motor in accordance with a detected torque that is detected by the torque detection unit. A suspending unit suspends the operation of the changing unit, until an absolute value of the detected torque becomes equal to or smaller than a predetermined value.

    摘要翻译： 电动机控制器控制包括转子和面对转子的定子的电动机。 电流驱动单元基于根据作为控制中使用的旋转角度的控制角旋转的旋转坐标系中的轴电流值来驱动电动机。 相加角度计算单元计算添加到控制角度的相加角度。 控制角计算单元通过在每个预定计算周期中将相加角加上控制角的紧接在前的值来获得控制角的当前值。 转矩检测单元检测除电动机转矩之外的施加于电动机从动部件的转矩。 改变单元根据由转矩检测单元检测到的检测转矩来改变用于控制电动机的参数。 暂停单元暂停改变单元的操作，直到检测到的转矩的绝对值变得等于或小于预定值。

    摘要： The present invention relates to a system (100) for controlling a synchronous machine (110) and a method (200) thereof. The system comprises: a flux linkage estimation module (120) for estimating one or more values of flux linkage (Ψ) in the synchronous machine (110) based on a regression-based model, an iron loss estimation module (130) for estimating one or more values of iron loss (P Fe ) in the synchronous machine (110) and a control module (140). The control module (140) receives the one or more values of flux linkage (Ψ) from the flux linkage estimation module (120) and the one or more values of iron loss (P Fe ) from the iron loss estimation module (130), and determines optimum current set points along a direct axis (I d *) and a quadrature axis (I q *) based on the values of flux linkage (Ψ) and iron loss (P Fe ) thereby controlling the synchronous machine (110).
