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.

“…Category (4) consists of many different approaches. Some proposed incorporating inverse hysteresis model with a controller while others proposed advance controllers like neural network [Hwang et al 2003], fuzzy logic [Stepanenko et al 1998], sliding mode [Abidi et al 2004] and H control [Chen et al 1999]. Category (5), a phenomenological approach, is about obtaining a mathematical representation of the hysteresis motion through observation.…”

“…Other research in the literature has focused on the development of intelligent control schemes for the precision control of PZTAs [1,2,[30][31][32][33][34][35][36][37]. Neural networks and fuzzy controls were also utilised to model the PZTA hysteresis non-linearities and control the micro/nano motion of the PZTA [1,32].…”

“…Some of these designs were based on the inverse hysteresis model that is assumed to be known a priori, so feedforward techniques can be utilised in the control design [30,33]. In [1,[34][35][36], feedback linearisation was utilised to compensate for the hysteresis dynamics and then tracking controllers were implemented. Wu and Zou [37] presented an inversion-based iterative control approach to compensate for both the hysteresis and the vibrational dynamics variations during high-speed, large-range tracking.…”

Abstract:In this study, the Coleman-hysteresis model is utilised in the piezoelectric actuator (PZTA) dynamic model and a non-linear robust control strategy is then developed to actively control the displacement of the PZTA effective tip. The proposed control technique is designed based on the partial knowledge of the hysteresis model while the mass of the PZTA is assumed to be uncertain. The piezoelectric charge measurement is utilised in the controller design to reduce the effects of the hysteresis. Lyapunov-based stability analysis techniques are utilised to ensure that a desired displacement trajectory is accurately tracked. Representative numerical results are presented and discussed to demonstrate the tracking performance of several desired displacement trajectories with different frequencies and amplitudes. Finally, comparisons with a standard PID controller and a sliding mode controller were performed to examine the effectiveness of the proposed control design.
