Abstract
A system for controlling the operation of a piezoelectric device including a control system operable to generate a first control signal representing a desired charge on the piezoelectric device and corresponding to a desired position of a piezoelectric device. The control system further includes a charge control circuit responsive to the first control signal for providing a charge control signal to a device control circuit. The device control circuit provides a command signal that causes the piezoelectric device to move to the desired position.
