| Abstract: | A novel miniature friction drive piezoactuator was presented. The system modeling of the piezoactuator was performed by using stick-slip friction model. The dynamic characteristics over various driving signals were investigated by comparing the simulation and experimental results. By varying the frequency and amplitude of driving signals, it is possible to control the moving direction and velocity of the actuator. That the simulation results agree well with the experimental results indicates that the friction model is capable of doing precise analysis for piezoactuator. |
