Abstract
An actual run-up ramp is measured for internal combustion engine-generator unit during a starting process. The actual run-ramp is then set as the set run-up ramp. In this way, the closed-loop control of the internal combustion engine-generator unit adapts itself to the on-site conditions.
Claims7
A method for closed-loop speed control of an internal combustion engine-generator unit during a starting process, comprising the steps of:
- presetting a set speed (nM(SW)) by means of a set run-up ramp (HLR(SW));
- computing a control deviation from the set speed (nM(SW)) and an actual speed (nM(IST));
- determining a set injection quantity (QSW) for controlling the actual speed (nM(IST)) from the control deviation by means of a speed controller;
- and, determining an actual run-up ramp (HLR(IST)) from the actual speed (nM(IST)), ((HLR(IST))=f(nM(IST))), and setting this as the set run-up ramp (HLR(SW)).
