Abstract

This study presents the controller design and experimental tests of a piezoelectric actuator (PEA) in precision positioning. The PEA output hysteretic model is synthesized based on the two first-order transfer function (TF) systems in parallel with two tuned parameters determined from experimentation. Two open-loop tracking controllers cooperated with TF model are implemented to compensate the hysteresis of linear positioning. Experimental tests on tracking sinusoidal and triangular waveforms with signal frequencies of 7.5-20 Hz and PEA traveling amplitudes of 4.22-14.82 μm are revisited and compared with Bouc-Wen and Duhem models. Experimental results show that the RMS tracking error can be reduced to less than 2% of the PEA maximum traveling distance at predetermined frequency. Furthermore, using the model reference control for additive compensation in the loop, experimental results consolidate that the RMS tracking error can be reduced to less than 4% of the maximum traveling distance with signal amplitudes of 30-100 V and approximates 4.5% with signal frequencies of 7.5-20 Hz.
