摘要： A method for obtaining data from a nonlinear dynamic real system during a test run, for instance an internal combustion engine, a drivetrain, or parts thereof, a sequence of dynamic excitation signals is generated according to an initial design and a system output is measured. To enable the quick and precise generation of experimental designs for global measurement, modeling, and optimization of a nonlinear dynamic real system, a sequence of dynamic excitation signals was generated by generating a design with a sequence of excitation signals, obtaining output data by feeding said sequence into a model for the real system, determining a criterion for the information content of the complete design of experiment sequence, varying the sequence, obtaining new output data by feeding said modified sequence into the model, determining again said criterion, iterating until said criterion improves, and using the improved sequence of excitation signals for the real system.

摘要： In a machine-implemented method for obtaining data from a nonlinear dynamic real system during a test run, for instance an internal combustion engine, a drive-train or parts thereof, of a sequence of dynamic excitation signals for at least one measurement channel is generated according to a previously generated design of experiment for said test run and the system output of at least one output channel is measured. To enable the quick and precise generation of experimental designs for global measurement, modeling, and optimization of a nonlinear dynamic real system, it is proposed that the sequence of dynamic excitation signals was generated by the method of generating a design of experiment with a sequence of excitation signals, obtaining output data by feeding said sequence of excitation signals into a model for the real system, said model comprising nonlinear dynamic models, determining a criterion for the information content of the complete design of experiment sequence, and in a following step varying the totality of the sequence of excitation signals, obtaining new output data by feeding said modified sequence of excitation signals into the model for the real system, determining again said criterion for the for the information content, and repeating these steps until said criterion has reached its optimum value, using the last generated sequence of excitation signals as design of experiment for the test run of the real system.
