Abstract
The embodiments relate to a method and to a device for operating a system including a generator and an internal combustion engine driving the generator, wherein a rotational speed of the generator is controlled by a rotational speed controller. In the method, the rotational speed controller outputs a target torque as manipulated variable, and an additional torque is imposed on the target torque, wherein the additional torque is calculated or is determined based on a measured value picked up from the system.
Claims16
A method for operating a system comprising a generator and an internal combustion engine that drives the generator, the method comprising:
- controlling a rotational speed of the generator by a rotational speed controller;
- outputting, by the rotational speed controller, a target torque as a manipulated variable;
- and
- imposing an additional torque on the target torque,
- wherein the additional torque is a torque that the generator applies counter to a pressure prevailing in a combustion chamber of the internal combustion engine or a torque to accelerate a rotor of the generator and a piston of the internal combustion engine,
- wherein the additional torque is calculated or determined based on a measured value picked up from the system.
An open-loop and closed-loop control apparatus comprising:
- at least one control unit;
- and
- a rotational speed controller,
- wherein the apparatus is configured to control a rotational speed of a generator of a system,
- wherein a target torque is configured to be output as a manipulated variable by the rotational speed controller, and
- wherein the apparatus is configured to impose an additional torque on the target torque, wherein the additional torque is calculated or determined based on a measured value picked up from the system.
A system comprising:
- a generator;
- an internal combustion engine;
- and
- an open-loop and closed-loop control apparatus having:
- at least one control unit;
- and
- a rotational speed controller,
- wherein the open-loop and closed-loop control apparatus is configured to control a rotational speed of the generator of the system,
- wherein a target torque is configured to be output as a manipulated variable by the rotational speed controller, and
- wherein the open-loop and closed-loop control apparatus is configured to impose an additional torque on the target torque, wherein the additional torque is calculated or determined based on a measured value picked up from the system.
