Abstract: According to the present invention, an analog evaluation circuit, the digitization and the conversion into physical variables are moved from the higher-order control system into the sensor system, and the control system is connected to this new sensor system through a synchronous high-speed transmission system. This serial real-time sensor interface provides the network capability of the transmission system and also permits simpler cabling.

Abstract: In a serial communication systems embodied as mono-master system in line topology, the invention achieves tolerance with respect to an arbitrary fault by using an additional return line to the master. This connection serves only for monitoring purposes during normal operation and it is only activated in the event of a line interruption, in order to undertake the communication to the “isolated” subscribers. In this case, two independent lines exist from the master to the slaves.

Abstract: A method and a device may be used for controlling the working points of a series-resonant-circuit inverter. The frequency of the inverter is controlled as a manipulated variable in dependence upon a defined phase-angle system deviation in such a way that a determined phase-angle actual value of a measurable state variable of the load circuit, whose phase-frequency characteristic has a monotonically falling curve, corresponds to a specifiable phase-angle setpoint value. Thus, a method and a device are implemented for controlling the working points of a series-resonant-circuit inverter, by which means the operating range prescribed for the series-resonant-circuit inverter is detected and kept stable independently of parameter fluctuations of the resonant circuit elements.

Abstract: A method and a device for controlling a sensorless, field-oriented asynchronous machine, wherein a manipulated variable space vector and a stator frequency are calculated, by means of a two-component current control system, from which control signals are generated using a space vector modulation process. A PI controller of an EMF control system for the d-component of a calculated EMR space vector of the field-oriented control system is deactivated and its output signal set to zero at a stator frequency, determined as a function of a calculated d-component of a calculated EMF space vector and a calculated stator frequency, that is less than or equal to a first limit frequency. Thus, the method may be used for speed control of a sensorless, field-oriented asynchronous machine down to a full stop.
