Abstract: A method and an apparatus for determining the individual manipulated variables of an internal combustion engine such as a gas turbine or the like derived on the basis of given and measured operating characteristics such as rpm and temperature, including a computer having associated programs for control and data detection or data output and the various program courses take place preferably in alternation. The control program is interrupted at fixed times, and during the interruption, a special program for data detection or data output is performed. The method of the invention makes input data available continuously, which then can be called up during the normal control program course from working memories and from time to time input and output data is brought up to the most recent state.

Abstract: A digital control apparatus for the running speed of a motor vehicle having an actual-value source, a memory for a demand-value which is proportional to the desired running speed, comparison means for executing an actual-value/demand-value comparison, and a setting device controlled by the output of the comparison means for controlling the throttle flap of an engine. Upon the actuation of a switch, the actual value is transferred into the demand-value memory apparatus and represents the running speed. To change the running speed by means of the control apparatus there is provided a second and auxiliary demand-value memory apparatus in which a ramp function is producible by means of a digital counting process. The given ramp value presents a supplementary demand-value during such an alteration of the running speed, i.e. the old running speed value is transformed into the new running speed value with the aid of the supplementary demand value.

Abstract: A preferred form of embodiment of the final control element comprises a direct-current electromagnet, with whose armature the regulator rod is connected; an inductive displacement transducer generating an electric output signal proportional to the stroke and having a pickup spool and a transducer rod connected to the regulator rod and influencing the inductivity of the pick-up spool in a stroke-proportional manner; and a restoring spring embodied as a helical compression spring, whose stroke-proportional restoring force acts counter to the attracting force of the magnet, which is proportional to the exciter current.
