Patent number: 9712095Abstract: A first active part of a poly-phase electric machine is connected to a converter having a control facility. The control facility updates a base commutation angle using the target speed value and determines direct-axis and quadrature-axis component values of currents and a commutation angle supplied to the machine. Target and component quadrature-axis values are provided to a quadrature-axis portion of a current controller that determines a target value of the quadrature-axis voltage component. Target and component current values are supplied to a direct-axis portion of the current controller, which determines a target value of the direct-axis voltage component therefrom. The target value of the direct-axis and quadrature-axis voltage components and the commutation angle are used to determine the target output voltages provided to the converter. A damping commutation angle determined using target values of the quadrature-axis and direct axis voltage components is used to adjust the of the voltage.Type: GrantFiled: November 17, 2015Date of Patent: July 18, 2017Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Daniel Bönke, Michael Jäntsch, Stefan Künzel, Carsten Spindler
