In general, precise linear actuators using piezoelectric element are driven by friction force. Exact understanding of friction plays and important role in analysis and control of a motor. In this research, we designed a precise linear actuator using piezoelectric elements and observed its dynamic characteristics. By varying phase angle difference and amplitudes of the sinusoidal waves that are driving inputs, we can know that it is possible to control moving direction and distance of the slider. As preload is increased, its moving distance is decreased. And also, we have modeled a precise linear actuator using stick slip friction models such as classical, Karnopp, and reset intergrator. Finally, by comparing the results of simulation and experiment, it was verified that the model is well designed.
