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.

Method for the closed-loop speed control of an internal combustion engine-generator unit

A method for engine speed control for an internal combustion engine generating unit () is disclosed, whereby a first time point is set when the actual speed (nM(IST)) exceeds a threshold value and a second time point set when the actual speed (nM(IST)) exceeds a start speed. A time span is then calculated from both time points. Depending on said time span, a run-up ramp and the regulation parameters for a speed regulator are selected.

Method for engine speed control

A method for closed-loop speed control of an internal combustion engine that is provided as a generator drive or a marine propulsion unit, including the steps of: computing a first control deviation (dR) from a speed variance comparison; computing a first set injection quantity (qV) from the first control deviation (dR) by a speed controller; determining a second set injection quantity (qV) from the first set injection quantity (qV) and another input variable (E) by a minimum value selector for the closed-loop speed control of the internal combustion engine, wherein in a first, steady operating state of the internal combustion engine, the input variable (E) corresponds to a first injection quantity (qV) (E=qV), which is computed via a first characteristic curve, and in a second, dynamic operating state of the internal combustion engine, the input variable (E) corresponds to a second injection quantity (qV) (E=qV), which is computed via a second characteristic curve; and changing from the first characteristic curve to the second characteristic curve when a changeover condition is satisfied.

Method for regulating the rotational speed of an internal combustion engine

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.

Method for controlling an internal combustion engine generator unit

A method for regulating the speed of an internal combustion engine. According to the invention, a second regulation difference (dR) is calculated by a second filter in the event of dynamic changes of state. In this way, in the event of dynamic changes of state, a speed regulator defines a power-determining signal (ve) according to a first regulation difference (dR) and the second regulation difference (dR). The inventive method thus increases the dynamics of the control loop.
