ABSTRACT:
A regulating device for an electromagnetic control element, especially for an internal combustion engine with auto-ignition, is proposed in which a non-linear regulator with preferably a PD characteristic is coupled with a pulse regulator, preferably a two-point regulator with PID characteristic. Of special advantage is the interposition of a limiting device, which allows an increase in the D portion of the non-linear regulator, while at the same time suppressing interference. This results in an excellent control behavoir, especially in the face of small control deviations and in a control element or control circuit afflicted with friction and/or (magnetic) hysteresis.
