Abstract

A piezoelectric strut exhibits hysteresis and creep due to the piezoelectric coefficient. These nonlinearities annoy a control engineer who uses the piezoelectric strut as a control actuator. Intensive experiments were performed by the authors to derive a linear model for the piezoelectric strut/power amplifier system. A servo-loop was designed to eliminate the nonlinearities. Experimental results of the open-loop and closed-loop systems are presented in this paper to validate the analytical model and control design.
