Abstract
Various embodiments of the present disclosure are directed to a method for carrying out a test run on a test stand. The method in some embodiments reduces a deviation between a comparison simulation value and a comparison reference value when carrying out a test run on a test stand with a test object by simulating via a simulation unit a number of simulation values using a number of specified reference values starting from a selected reference value, determining a corrected reference value which is specified to the simulation unit for simulating a corrected simulation value and determining at least one setpoint variable using the corrected simulation value.

Method for carrying out a test run on a test stand with a test object, the method including the steps of:
- defining a number of reference values with a reference unit and providing the reference values to a simulation unit,
- simulating the test object moving on a test track and generating a number of simulation values with the simulation unit using the number of reference values, wherein at least one setpoint variable and at least one control variable for controlling the test object is determined from the number of simulation values,
- detecting, via a detection unit, a deviation between a comparison simulation value from the number of simulation values and a comparison reference value from the number of reference values,
- when the deviation is detected, determining a corrected reference value, via a correction unit, starting from a selected reference value from the number of reference values,
- defining the corrected reference value for the simulation unit, wherein the simulation unit uses the corrected reference value instead of the selected reference value to generate a corrected simulation value, and
- determining at least one corrected setpoint variable using the corrected simulation value.
Test stand with a test object for carrying out a test run, the test stand comprising:
- a reference unit configured and arranged to define a number of reference values and to transmit the number of reference values to a simulation unit,
- the simulation unit configured and arranged to:
- generate a number of simulation values using the number of reference values,
- determine at least one setpoint variable from the number of simulation values and
- transmit the at least one setpoint variable to a control unit,
- the control unit configured and arranged to define at least one control variable for controlling the test object based on the at least one setpoint variable,
- a detection unit configured and arranged to detect a deviation between a comparison simulation value from the number of simulation values and a comparison reference value from the number of reference values, and
- a correction unit configured and arranged to determine a corrected reference value starting from a selected reference value from the number of reference values, when a deviation is detected, and to define the corrected reference value instead of the selected reference value for the simulation unit for generating a corrected simulation value, to determine at least one corrected setpoint variable using the corrected simulation value.
