Abstract
A motion control system and method for controlling a stick-slip piezo motor includes an electronic controller and an analog driver for moving a mechanical device. When operating in a digital circuit mode, an electronic controller controls a digital-to-analog converter for moving the stick-slip piezo motor at a low speed. When operating in a faster analog circuit mode, the electronic controller, via an analog driver, operates to control an analog hardware circuit to move the stick-slip piezo motor at a high speed. The electronic controller operates in the digital circuit mode at start-up of the piezo motor.
