Method and device for ascertaining a physical variable in a position transducer system

摘要

A method for ascertaining a value of a physical variable in a position transducer system includes the steps of providing a computation model, which maps a response of the position transducer system, wherein the computation model includes a model function and one or multiple parameter(s); ascertaining a value of at least one system variable at one or multiple points in time; determining the parameters of the computation model from one or multiple value(s) of the at least one system variable determined at different points in time; and determining the value of the physical variable as a function of the one or the multiple determined parameters.

1. A method for operating a position transducer system, comprising:
providing, using a control unit of the position transducer system, a computation model, which maps a response of the position transducer system, the computation model including a model function and one or multiple parameters; ascertaining, using a position sensor of the position transducer system, a value of at least one system variable at multiple points in time; determining, using the control unit, the parameters of the computation model from one or multiple values of the at least one system variable determined at different points in time; determining, using the control unit, a value of a physical variable at at least one of the multiple points in time as a function of the one or the multiple determined parameters; and providing, using the control unit, a control signal to a position transducer drive of the position transducer system as a function of the determined value of the physical variable.
