Title:
METHOD FOR THE OPEN-LOOP AND CLOSED-LOOP CONTROL OF AN INTERNAL COMBUSTION ENGINE WITH A GENERATOR AND ASYNCHRONOUS MACHINE, OPEN-LOOP AND CLOSED-LOOP CONTROL UNIT, AND INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/138034
Kind Code:
A1
Abstract:
The invention relates to a method for the open-loop and closed-loop control of an internal combustion engine (BK), in particular a diesel engine or gas engine, with a generator (G) and asynchronous machine (ASM), comprising the following steps: detecting at least one electrical characteristic variable of the generator, wherein the electrical characteristic variable is selected from current (I), voltage (U) or frequency (f); determining a characteristic variable change in the electrical characteristic variable of the generator in a predetermined time interval; comparing the change in characteristic variable with a first threshold value; and in the event that the change in characteristic variable is greater than the first threshold value, changing from a standard speed control of the internal combustion engine to a feed-forward control.
