Abstract
The excitation of a system is a crucial task in system identification. If the data was not captured with persistent excitation, the parameter estimation degrades and the parameter variance increases. Application of Design of Experiment (DoE) algorithms helps to overcome these problems. This work presents the extension of the well known Wynn-Algorithm for non-linear but static systems to non-linear dynamic systems. Instead of optimizing the input only for the next sampling instant, an input sequence is optimized over a receding horizon.
The developed algorithm is used to identify the model of a hydrodynamic brake used on a combustion engine test bench as load machine.
