Abstract
The hysteresis characteristic of piezoelectric actuators makes precise position control very difficult. In this study a tracking control method for a piezoelectric actuator based on PID controller augmented with a feedback linearization loop based on the Maxwell slip model is presented. Further, the controller design is extended to include a repetitive controller. Experiments were performed on a piezoelectric 2-axis linear positioner for tracking sinusoidal waveforms and circles. The experimental results show that the tracking control performance is noticeably improved by augmenting PID controller with feedback linearization loop and repetitive controller.
