“…Some of the earlier research [17,[26][27][28][29] was devoted to improve the PZTA control strategies by reducing the effects of the non-linearities in the PZTA dynamic models which was achieved by applying electric charge feedback information instead of applied voltage. In [26,27], researchers demonstrated that voltage to displacement linearisation of a PZTA may be achieved if the control input is the applied electric charge rather than the applied voltage.…”

“…In [26,27], researchers demonstrated that voltage to displacement linearisation of a PZTA may be achieved if the control input is the applied electric charge rather than the applied voltage. Furutani et al [28] was able to improve the PZTA control strategy by combining induced charge feedback with an inverse transfer function compensation.…”

“…The dynamic model of the PZTA is based on Coleman-Hodgdon hysteresis model in [45]. Since charge feedback controllers reduce the effects of the non-linearities in the PZTA dynamic model and provide better performance over the voltage feedback controllers [17,[26][27][28][29]46] the electric charge feedback is utilised in the controller design to reduce the effects of the hysteresis in the PZTA dynamic model. The feedback charge of the PZTA is obtained by measuring the voltage across a capacitor that is added in-series to the PZTA circuit.…”

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.

“…A linear dynamic relationship between the excitation force and the actuator displacement is also present (9). Although the effect of hysteresis could be bypassed with control of the induced charge, costly instrumentation is required for the measurement and amplification of the induced charge (10,11). Voltage drive strategies are thus preferred, despite their limiting hysteresis non-linearity.…”

Background Intracytoplasmic sperm injection (ICSI) requires long training and has low success rates, primarily due to poor control over the injection force. Making force feedback available to the operator will improve the success rate of the injection task. A macro-micro-teleoperation system bridges the gap between the task performed at the micro-level and the macroscopic movements of the operator. The teleoperation slave manipulator should accurately position a needle to precisely penetrate a cell membrane. Piezoelectric actuators are widely used in micromanipulation applications; however, hysteresis non-linearity limits the accuracy of these actuators.
