A method for managing computing performance in a real-time data processing system, having at least one apparatus for controlling at least one computing device that is embodied for execution of a first and of at least one further application, at least the first application encompassing at least one anytime algorithm. The method includes: assigning a first computing-performance budget, as a function of a first point in time, to the first application; activating the computing device for execution of the first application, at the first point in time by the computing device; checking whether, after execution of the first application, a portion of the first computing-performance budget is still available and, in the event a portion of the budget is still available, performing (i) activating the computing device for re-execution of the first application, or (ii) assigning the portion of the first computing-performance budget to at least one further application.

Method and apparatus for managing computing performance in a data processing system

The invention provides a device () and a method for controlling an electric machine (). The method comprises the steps of: providing (S) a desired torque value () for a torque to be exerted by the electric machine (); determining (S) a fault signal () which indicates a fault state of the electric machine (); determining (S) a current rotor angle value () of the electric machine (); determining (S) a fault state operating point () on the basis of the desired torque value () provided, the determined fault signal () and the determined current rotor angle value (); and shifting or moving (S) an operating point, at which the electric machine () is operated, from a normal state operating point () to the determined fault state operating point ().

Device and method for controlling an electric machine

The invention relates to an apparatus for estimating angles in a synchronous machine (), having an angle sensor device () which is designed to determine event-discrete measured values for a rotor angle (&#x3c6;) of a rotor of the synchronous machine () and to output a measurement signal dependent on the determined measured values, an estimation device () which is designed to record current and/or voltage signals from the synchronous machine (), to calculate a deviation (&#x394;&#x3c6;) of the rotor angle (&#x3c6;) of the rotor of the synchronous machine () from an expected rotor angle on the basis of the recorded current and/or voltage signals and to output a deviation signal dependent on the calculated deviation (&#x394;&#x3c6;), and a combining device () which is designed to receive the measurement signal and the deviation signal and to calculate an estimated value ({circumflex over (&#x3c6;)}) for the rotor angle (&#x3c6;) of the rotor of the synchronous machine () from a combination of the measurement signal and the deviation signal.
