A driving power with filter compensator for micro-positioning improvement of piezoelectric bimorph actuators

Piezoelectric bimorph has the advantages of small size, low power consumption and high operating frequency. Meanwhile, it has the short-comings of small displacement of deformation and weak driving force applying to the load. Piezoelectric bimorph actuators can replace the previous electromagnetic needle selector successfully by means of displacement magnifying mechanism and other auxiliary mechanism. An innovative piezoelectric jacquard selection mechanism has been designed in the paper.

Piezoelectric bimorph actuators have been employed in several applications. In this paper, the piezoelectric actuator is discretized and its hysteresis function is studied, then a digital sliding mode controller is designed. Furthermore, a perturbation estimation technique is applied and an observer is no longer needed. In addition, simulations are performed also using the traditional PID controller in order to validate the proposed controller scheme performance.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
