If the best electrical drive signal for the piezoelectric actuator in an inertia motor is to be determined, its dynamical behaviour must be known. A classic dynamic lumped parameter model for piezoelectric actuators is valid only in resonance and, therefore, is not suitable for modelling the actuator in an inertia motor. A reduced dynamic model is used instead. Its parameters are identified using a step response measurement. This model is used to predict the movement of the actuator in response to a velocity-optimized signal introduced in a separate contribution. Results show that the model cannot represent the dynamical characteristics of the actuator completely. For determining voltage signals that let piezoelectric actuators follow a calculated movement pattern exactly, the model can, therefore, only be used with limitations."}],"publication":"Journal of Korean Physical Society","type":"journal_article","date_updated":"2022-01-06T07:04:19Z","language":[{"iso":"eng"}],"department":[{"_id":"151"}],"publication_identifier":{"issn":["1948-5719"]},"title":"Parameter Identification and Model Validation for the Piezoelectric Actuator in an Inertia Motor","_id":"9752","volume":57,"citation":{"bibtex":"@article{Hunstig_Hemsel_2010, title={Parameter Identification and Model Validation for the Piezoelectric Actuator in an Inertia Motor}, volume={57}, DOI={<a href=\"https://doi.org/10.3938/jkps.57.952\">10.3938/jkps.57.952</a>}, number={4}, journal={Journal of Korean Physical Society}, author={Hunstig, Matthias and Hemsel, Tobias}, year={2010}, pages={952–954} }","chicago":"Hunstig, Matthias, and Tobias Hemsel. “Parameter Identification and Model Validation for the Piezoelectric Actuator in an Inertia Motor.” <i>Journal of Korean Physical Society</i> 57, no. 4 (2010): 952–54. <a href=\"https://doi.org/10.3938/jkps.57.952\">https://doi.org/10.3938/jkps.57.952</a>.","short":"M.
