Abstract
A method for operating a load dependent current-generating system which supplies at least one electric drive motor with electrical energy. A power request is made to the electric drive motor, and a dynamic parameter of the current generating system and/or a simulation model, which characterizes the behaviour of the current generating system, is used for calculating the setpoint current value for the current generating system.
Claims14
A method for generating a setpoint current value for a load-dependent current-generating system which supplies an electric drive motor with electrical energy, said method comprising the steps of:
- providing a power request (LA) to the electric drive motor;
- providing at least one of a dynamic parameter of the current-generating system and a simulation model which characterizes behaviour of the current-generating system;
- and
- calculating a setpoint current value (Isetp) as a function of said at least one of a dynamic parameter of the corresponding system and a simulation model.
A method of compensating for the dynamic behaviour of a current-generating system, comprising the steps of:
- scaling a dynamic parameter of the current-generating system by dividing the dynamic parameter by a number of time units;
- and
- subsequently taking a measured value of a variable in order to ensure a time reference frame for all variables to be used.
