“…The whole model is often referred to as Butterworth Van Dyke (BvD) model, and it provides more accurate results than the only RLC series circuit. Alternative models, which take into account other non-idealities of the resonant device are: the Guan model [34] and the transmission line model for piezoelectric sensors [35]. In this paper, the accuracy of the BvD model will be proved to be sufficient for the purpose of this work.…”

Abstract:In this paper, we characterize and model a bidirectional front-end based on pseudo-floating gate amplifier (PFGA) for actuation and read-out of resonating sensors. The basic idea consists of swapping the power supply of the PFGA in order to change the directionality of the front-end. A detailed description of the system has been discussed in this paper and supported by simulations and measurement results. A prototype has been fabricated using discrete components and tested with a real transducer (Murata MA40S4) and a Butterworth Van Dyke (BvD) load, which has proved to be proved to be a well approximated model for resonant sensors. The bidirectional amplifier has been implemented with the integrated circuit CD4007UB, which is a commercial discrete component containing low leakage MOSFET. The values chosen for the BvD load are R b = 330 Ω, L m = 60 mH, C s = 450 pF, C E = 2.2 nF, which are approximately the same values of the lumped parameters reported in the data-sheet of the real sensor. This transducer is characterized by a nominal resonant frequency of 40 kHz. Measurement results show good fitting with the models developed in this work and the possibility to predict the sensor response by using the BvD load.

The paper addresses the practical implementation of active vibration control using self-sensing actuators, intending to equip smart structures. The control objective is to reduce the structural vibration of a simply-supported plate subject to time-harmonic excitation. The key challenge is to use a self-sensing actuator instead of a sensor-actuator pair to reject the primary disturbance at the control point. In this study, two types of self-sensing actuators designed from a PZT patch and an electrodynamic inertial exciter are discussed, and their overall performance is compared in terms of reduction of flexural energy and power consumption. Both technologies have proven to be efficient in achieving a timeharmonic vibration control and may be used alternately, depending on the application at hand.

“…The Van Dyke circuit model, adopted by the IEEE Standard on Piezoelectricity, is the best known circuit, although various enhancements to this circuit have been proposed to better represent the nonlinear effects of piezoelectric actuators [10], [11]. This paper adopts the equivalent circuit of [10], shown in Fig. 1.…”

Abstract-Piezoelectric actuators can achieve high efficiency and power density in very small geometries, which shows promise for microrobotic applications, such as flapping-wing robotic insects. From the perspective of power electronics, these actuators present two challenges: high operating voltages, ranging from tens to thousands of volts; and a low electromechanical coupling factor, which necessitates the recovery of unused electrical energy. This paper explores the power electronics design problem by establishing the drive requirements of piezoelectric actuators, presenting circuit topologies and control methods suitable for driving different types of piezoelectric actuators in microrobotic applications, and demonstrating experimental realizations of sub-100mg power electronics circuits.
