摘要： The invention relates to a method (40) for monitoring a torque of an electric motor (10), in particular for application in a motor vehicle, wherein the electric motor (10) is supplied with electric current (IS1, IS2, IS3) in multiple phases. A first torque value (M2) of the torque generated by the electric motor (10) is determined (58) on the basis of the electric output of the electric motor (10) and a detected rotational speed (n) of a rotor of the electric motor (10). A second torque value (M1) is determined on the basis of at least one measured phase current (IS1, IS2, IS3) and a rotational position of the rotor, and the two determined torque values (M1, M2) are compared (60) to one another for plausibility checking.

摘要： A current estimation section of a motor control apparatus carries out the following processing. When an AC motor is controlled under a current feedback control scheme (sine wave control mode or overmodulation control mode), a β-axis current iβ is calculated based on a current detection value iw_sns in a sensor phase and a current command value iv* in one other phase. When the AC motor is controlled under a torque feedback control scheme (rectangular wave control mode), the β-axis current iβ is calculated based on a differential value Δiα of an α-axis current. Then a sensor phase reference current phase θx is calculated to estimate a U-phase current. Thus it is possible to use the current feedback control scheme and the torque feedback control scheme together.

摘要： A vehicle includes one or more inverter-fed electric machines such as permanent magnet synchronous motors. In response to a torque request, a controller issues commands to an inverter calculated to cause the motor to produce the requested torque. A method of operating the inverter may determine the commands based on the ratio of rotor speed to inverter input voltage, reducing the approximation error associated with multi-dimensional lookup tables. When the speed and voltage vary while maintaining a constant ratio and constant torque request, the issued commands produce a winding current in the electrical machine with constant direct and quadrature components.

摘要： A motor control circuit calculates an α-axis current iα and a β-axis current iβ in a fixed coordinate system based on a W-phase (sensor phase) of an AC motor. The control circuit calculates the α-axis current iα from a current iw.sns sensed in the W-phase, and the β-axis current iβ from a differentiated value Δiα determined from the variation quantity of the α-axis current based on that the α-axis current iα and the β-axis current iβ are in a relation of a sine wave and a cosine wave. Subsequently, the control circuit calculates a current phase xθ=tan−1(iβ/iα) relative to the W-phase. Subsequently, the control circuit calculates an estimation factor according to the current phase xθ and determines an estimated current iu.est in the U-phase of the AC motor by multiplying the sensed current iw.sns by the calculated estimation factor.

摘要： Disclosed is a method for suppressing a speed ripple occurring during an operation of an AC motor by using a torque compensator based on an activation function. The method includes the steps of calculating a speed error ωerr based on a reference speed ωref and an actual speed ωact; calculating a controller output Trm by using the speed error ωerr as an input of a PI control and an operation of a compensated torque Tcom; and determining a torque variation based on the controller output Trm and a reference torque Tref and operating the torque variation in relation to an anti-windup gain Ka to use torque variation as an input of an integral (I) control. The method suppresses the speed ripple by compensating for the torque ripple through a controller which calculates the compensated torque by taking the signs of the speed error and the differential speed error into consideration.

摘要： In a drive system of an AC motor in which a motor current is feedback-controlled, a motor current command is produced in a normal operation according to a torque command value on an optimum efficiency characteristic line so as to select an optimum current phase maximizing an output torque with a constant motor current amplitude. Conversely, when the AC motor produces an excessively generated power exceeding a regeneratable power quantity of the AC motor, a consuming operation is performed for intentionally increasing the power loss in the AC motor. In the consuming operation, the motor current command is produced according to the torque command value on a loss increase characteristic line to change the current phase from the above optimum value. Thereby, the power loss in the AC motor can be increased to consume the surplus power without causing instability in the motor control.
