Electric actuators are an important part of every manufacturing system. Often it is a problem to get a good motion control configuration which allows high performance tasks. This contribution shows how the mechanical load and the self-dynamics of the system associate. Based on this, it is possible to formulate an identification algorithm to estimate the mechanical load. Now all system parameters are known and the controller can compute automatically. Therefore we show the results in an experiment with a classic cascaded and a flatness-based controller.
