Patent ID: 7207305

Claim:
A method for closed-loop speed control of an internal combustion engine-generator unit during a starting operation, comprising the steps of: presetting a set speed (nM(SW)) by means of a run-up ramp (HLR), which begins with a starting speed (nST) and ends with a rated speed (nNN); determining a control deviation from a comparison of the set speed and actual speed (nM(SW), nM(IST)); computing a power-determining signal (QP) for controlling the actual speed (nM(IST)) from the control deviation by a speed controller; setting first time (t 1 ) when the actual speed (nM(IST)) exceeds a limit (GW), i.e., (nM(IST)>GW); setting a second time (t 2 ) when the actual speed (nM(IST) exceeds the starting speed (nST), i.e., (nM(IST)>nST); computing a time interval (dt) from the difference of the two times (t 1 , t 2 ); and selecting the run-up ramp (HLR) and the controller parameters of the speed controller as a function of the time interval (dt).
