Method for the computer-aided determination of a control variable,controller, regulating system and computer program product
First Claim
1. A method for computer-assisted determination of a control variable using context information from a unit to be controlled, comprising:
- determining simulated context information at a controller using a simulation, the simulated context information including a first variable which represents an assumed state of the unit to be controlled at a given point in time;
using the simulated context information as a control variable;
receiving actual context information including a second variable, which represents an actual state of the unit to be controlled at a point in time which is before the given point in time;
comparing, at the controller, the actual context information with the simulated context information to determine whether the simulated context information corresponds with the actual context information within predetermined limits; and
requesting updated context information from the unit to be controlled if the simulated context information is outside the predetermined limits with respect to the actual context information at the given point in time, the controller requesting the updated context information, whereinthe controller repeatedly requests updated context information according to an update frequency, andthe update frequency is decreased if the first and second variables match or increased if the first and second variables do not match.

Abstract
A method for the computer-aided determination of a control variable using context information from one or more units to be controlled is described. This method involves a controller using simulation to ascertain a piece of simulated context information which is used as a control variable, wherein the simulated context information comprises a first variable which represents a presumed state of the one or more units at a given time. The controller compares a received piece of context information, which comprises a second variable which represents the actual state of the unit to be controlled at a time which is before the given time, with the simulated context information and checks whether the simulated context information matches the context information within prescribed limits. In addition, the controller requests a piece of updated context information from one or more units to be controlled if the simulated context information matches the context information at the given time outside the present limits.
