“…However, the controller would have little authority over the second and third modes as evident from the low profile of these two modes in the ([2,2]) plot, if this pair was to be used in a SISO setting. This situation is reversed for the second collocated pair ( [3,3]). The reason for this can be explained by examining the first three vibrational mode shapes of a cantilever beam in Fig.…”

Abstract-Driving piezoelectric actuators by charge, or current rather than voltage is known to significantly reduce the hysteretic nature of these actuators. Although this feature of piezoelectric transducers has been known to the researchers for some time, still voltage amplifiers are being used as the main driving mechanism for piezoelectric devices. This is due to the perceived difficulty in building charge/current amplifiers capable of driving highly capacitive loads such as piezoelectric actuators. Recently, a new charge amplifier has been proposed which is ideal for driving piezoelectric loads used in applications such as active damping of vibration. Consequently, it is now possible to effectively, and accurately control the charge deposited on the electrodes of a piezoelectric transducer, and thereby avoid hysteresis altogether. This paper further investigates properties of piezoelectric transducers driven by charge sources when used with resonant controllers for structural vibration control applications. The paper reports experimental results of a multivariable resonant controller implemented on a piezoelectric laminate cantilever beam.

“…The phenomenological models are formulated based on a purely mathematical expression that relates the overall inputoutput relationship without considering the underlying physical essence. Several examples of such models are the generalized Maxwell model, 15,16 the Prandtl-Ishlinskii model, 17 and the Preisach model. [18][19][20][21][22][23][24][25][26] However, the symmetric structures of the generalized Maxwell and the Prandtl-Ishlinskii model limit their accuracy.…”

The hysteresis characteristic in macro fibre composite (MFC) actuator is intimately related to their application in vibration control system. In this paper, the electromechanical hysteresis property of MFC actuator is studied. First, experimental study on the electromechanical behaviours under different voltages and frequencies is carried out, and the hysteretic property of MFC actuator is investigated. A digital signal processing (DSP) system is used to control input voltage and a digital image correlation (DIC) system as noncontact setup is used to obtain the output strain of the MFC actuator in the experiment. The experimental results indicate that the relationship of the voltage and strain displays hysteresis with nonlocal memory. Second, the Preisach model is used to describe hysteresis characteristic of the MFC actuator. In order to improve the accuracy of the model, the modifications are made, in which the experimental data under the quasi-static frequency range and the congruency property are used to establish the modified Preisach model. Finally, the hysteresis characteristics of the MFC actuator predicted from the proposed model are compared with those obtained from the classical Preisach model. The results indicate that the proposed model gives better accuracy than the classical Preisach model, and it is suggested that the present study on the hysteresis model of the MFC actuator can be used in the active vibration control.

Piezoelectric energy harvesting: State-of-the-art and challenges Applied Physics Reviews 1, 031104 (2014) In this paper, a utility piezoelectric energy harvester with low frequency and highoutput voltage is presented. Firstly, the harvester's three theoretical models are presented, namely the static model, the quasi static model and the dynamic vibration model. By analyzing the influence of the mass ratio of the mass block to the beam on output characteristics of the harvester, we compare the quasi static model and the dynamic vibration model and then define their applicable ranges. Secondly, simulation and experiments are done to verify the models, using the harvester with PZT-5H piezoelectric material, which are proved to be consistent with each other. The experimental results show that the output open-circuit voltage and the output power can reach up to 86.36V and 27.5mW respectively. The experiments are conducted when this harvester system is excited by the first modal frequency (58.90Hz) with the acceleration 10m/s 2 . In this low frequency vibration case, it is easy to capture the energy in the daily environment. In addition, LTC 3588-1 chip (Linear Technology Corporation) is used as the medium energy circuit to transfer charges from the PZT-5H electrode to the 0.22F 5V super capacitor and ML621 rechargeable button battery.
