A method for real-time testing of a control unit with a simulator is provided. The simulator calculates a load current and a load voltage as electrical load state variables via converter control data and via an electrical load model that does not take into account current discontinuities caused by the converter, and transmits at least a portion of the load state variables to the control unit. A control observer is additionally implemented on the simulator that calculates at least the load current as a load state variable taking into account the converter control data and an observer load model. The observer detects a zero-crossing of the load current and a current discontinuity caused thereby from the calculated load current, and upon detection of a current discontinuity the observer calculates an electrical compensating quantity.

Computer-implemented method for real-time testing of a control unit

A device for transmission and/or generation of torque having a driveshaft and having a driven shaft acted upon by field-excited forces of a magnetorheological medium, the driveshaft terminates in a flange in a housing, at least one cylinder is arranged on the flange (), and the cylinder extends over the driven shaft coaxially while forming a gap which is filled with the magnetorheological medium.
