Design and Experimental Research of a Novel Stick-Slip Type Piezoelectric Actuator
A linear piezoelectric actuator based on the stick-slip principle is presented and tested in this paper. With the help of changeable vertical preload force flexure hinge, the designed linear actuator can achieve both large travel stick-slip motion and high-resolution stepping displacement. The developed actuator mainly consists of a bridge-type flexure hinge mechanism, a compound parallelogram ...
متن کاملThermal effect on piezoelectric stick-slip actuator systems.
The piezoelectric stick-slip (PZT-SS) actuator is known to achieve motion with a theoretically unlimited range yet high resolution (several nanometers). In this type of actuator, friction plays an active role in producing a meaningful stick-slip motion. However, friction is a source of heat which may cause significant temperature rise, affecting the dynamic performance of the actuator. Our stud...
متن کاملRotary Steerable Directional Drilling Stick/Slip Mitigation Control
This paper details the online-identification-based adaptive design of a stick/slip minimization algorithm and top-drive servo control for Rotary Steerable System (RSS) directional drilling tools. Stick/slip in this context refers to the downhole angular velocity variation of the bit about a nominal value. The basic pole placement controller designs are SISO linear but recursively evaluated base...
متن کاملAn ARX-Based PID-Sliding Mode Control on Velocity Tracking Control of a Stick-Slip Piezoelectric-Driven Actuator
Piezoelectric-driven stick slip actuators have been drawn more and more attention in the nanopositioning application due to the high accuracy and theoretical unlimited displacement. However, the hysteresis of piezoelectric actuator (PEA) and the nonlinear friction force between the endeffector and the stage make control of piezoelectric-driven stick slip actuator challenge. This paper presents ...
متن کاملDesign, Prototyping, and Characterization of an Innovative Piezoelectric Rotary Actuator
An innovative actuation principle is introduced in this paper to drive a rotary motor using an anisotropic piezoelectric composite laminate. The driving element is a three layer laminated beam with piezoceramics sandwiched between two anti-symmetric composite laminae. By taking advantage of material anisotropy, torsional motion can be induced from in-plane strain actuation. With such structural...
