A Novel Charge Control Circuit for Piezoelectric Actuators Driven by High Voltage
A Novel Charge Control Circuit for Piezoelectric Actuators Driven by High Voltage
This paper reports a work on developing a novel charge control circuit for control of the piezoelectric actuator to overcome its hysteresis nonlinearity when the actuator is driven at high voltage (as opposed to low voltage reported in literature). The charge control circuit also includes a balancing resistor. A test-bed for a piezoelectric actuator was established and an experiment was conducted. The result showed that the hysteresis nonlinearity of the piezoelectric actuator was reduced by 82% under the proposed charge control circuit. This charge control circuit can be used for control of piezoelectric inertia-friction actuator, in which the piezoelectric actuator is part of the whole actuator system.
