Abstract
A method for the closed-loop speed control of an internal combustion engine-generator unit with a coupling, in which method, when the engagement of the coupling is detected, a change is made from a first set of parameters to a second set of parameters. In the second set of parameters, a second run-up ramp is set, which determines the presetting of the set speed, and second controller parameters are set as the determining factors for computing controller components of a speed controller.
Claims10
A method for closed-loop speed control of an internal combustion engine-generator unit with a coupling during a starting operation, comprising the steps of:
- using a first set of parameters (PARA1) to select a first run-up ramp (HLR1) for the set point assignment of a set speed (nM(SL));
- using first controller parameters (TN1, kp1, Tv1) for computing controller components of a speed controller;
- and, during the starting operation after a start of the first run-up ramp (HLR1), selecting a second set of parameters (PARA2) when it is detected that the coupling has engaged, and deactivating the first set of parameters (PARA1), whereby the second set of parameters (PARA2) is used to set a second run-up ramp (HLR2) which determines the presetting of the set speed (nM(SL)), and to set second controller parameters (TN2, kp2, Tv2) as material for computing controller components of the speed controller.
