Test stand i.e. servohydraulic test stand, starting method for electrical testing and/or material testing in automobile industry, involves iteratively determining control signals based on linear models and correction transfer function

摘要

The method involves considering non-linearity of a test stand by amplitude values of cut target signals, where deviation of the cut target signals from uncut target signals is reduced. Control signals are iteratively determined based on linear models. The linear models are modified by scaling amplitudes of inverse transfer function by considering partial coherence. The control signals are iteratively determined based on a correction transfer function. The correction transfer function is determined by using actual time slots and comparison of theoretical and actual detection signals. An independent claim is also included for an arrangement for executing a method for starting a test stand.
