摘要： An open-loop and/or closed-loop control device for operating an asynchronous machine which is fed by a 3-phase power converter. The open-loop and/or closed-loop control structure has a stator flux controller and a pulse pattern generator for generating pulse signals based on mean values. An output of the stator flux controller is connected to an input of the pulse pattern generator, with the result that the pulse pattern generator can generate the pulse signals as a function of a manipulated variable which is generated by the stator flux controller. The stator flux controller is configured so as to generate the manipulated variable as a function of a desired value of the stator flux of the asynchronous machine and as a function of a desired value of the torque of the asynchronous machine. The stator flux controller has a dead-beat control response.

摘要： A method and a structure operate a three-phase machine, which is fed by a three-phase converter, using a stator flux regulator and either a slip frequency regulator or a torque regulator. A torque-forming fundamental-frequency current component of the stator current is limited by limiting a setpoint value that is supplied to the slip frequency regulator or to the torque regulator to a maximum slip frequency value maximum torque value. The flux-forming fundamental-frequency current component of the stator current is limited by limiting the speed at which a setpoint value supplied to the stator flux regulator changes to a maximum value. The maximum slip frequency value or maximum torque value is calculated on the basis of a prescribed maximum current value for a stator current fundamental-frequency magnitude of the stator current and on the basis of a filtered actual value of the flux-forming fundamental-frequency current component of the stator current.
