Abstract | ||||
In this paper, the static and dynamic characteristics of piezoelectric actuators (micromanipulator) are investigated theoretically and experimentally. A physical measurement setup is established for bimorph bending actuators. The actuator deflection is calculated for different driving voltages and compared with the measured values. Transient response due to a step input was very fast, the bandwidth obtained was 101Hz.The Transient, and frequency responses are obtained under different operating conditions. | ||||
