Novel multirate control strategy for piezoelectric actuators

In this article, a novel control method is proposed for feedforward compensation of hysteresis non-linearity in various frequency ranges. By integrating a multirate hysteresis compensator controller with PID feedback control, a combined controller is developed and experimentally validated for a piezoelectric micro-positioning system. Piezoelectric materials show non-linear hysteresis behaviour ...

A Novel Piezoelectric Energy Harvester Using the Macro Fiber Composite Cantilever with a Bicylinder in Water

A novel piezoelectric energy harvester equipped with two piezoelectric beams and two cylinders was proposed in this work. The energy harvester can convert the kinetic energy of water into electrical energy by means of vortex-induced vibration (VIV) and wake-induced vibration (WIV). The effects of load resistance, water velocity and cylinder diameter on the performance of the harvester were inve...

Optimal Shape Control of Composite Thin Plates with Piezoelectric Actuators

Emerging technologies in microsensing, microactuation, active airfoils, turbine blades, and large, lightweight, flexible space structures can benefit from piezoelectric actuators for active shape control. Piezoelectric materials develop strain under applied voltage which induces structural deflection. This article presents analytical models, FEM solution, and optimal shape control of composite ...

Multipulse Chaotic Dynamics for a Laminated Composite Piezoelectric Plate

We investigate the global bifurcations and multipulse chaotic dynamics of a simply supported laminated composite piezoelectric rectangular thin plate under combined parametric and transverse excitations. We analyze directly the nonautonomous governing equations of motion for the laminated composite piezoelectric rectangular thin plate. The results obtained here indicate that the multipulse chao...
