Improvements of Piezo-Actuated Stick–Slip Micro-Drives: Modeling and Driving Waveform [PDF]
Coatings, 2018 Modeling and waveform optimization are important research topics for piezo-actuated stick–slip micro-drives. In this paper, the dynamics of piezo-actuated stick–slip micro-drives (PASSMDs) are theoretically investigated. We introduce an extended model taking the dynamics of the piezo actuators into account.
