Summary: Hysteresis affects the accuracy of a piezoelectric nanopositioning system, leading to difficulties in maintaining satisfactory performance with inverse hysteresis model-based control. Linear active disturbance rejection control (LADRC) is a practical approach, but the phase lag of total disturbance estimation impacts its ability. By introducing a phase-leading extended state observer (PLESO), the system can compensate for total disturbance in a more timely manner, improving positioning accuracy.

Summary: This paper proposes a structured H∞ design to address the issues of accuracy and robustness caused by the weakly damped resonant modes and model uncertainty in a piezoelectric nanopositioning platform. A two-loop control structure is used, with an H∞ optimization matrix containing multi-dimensional performance decoupling outputs and an inner damping controller set according to the resonant modes' damping. Simulation experiments demonstrate that the designed structured H∞ controller achieves higher tracking accuracy and robustness compared to other controllers, meeting multiple performance requirements and showing suitability for engineering practice applications.

Summary: In this paper, a composite control strategy combining stepping and scanning modes is proposed to overcome the difficulties in achieving nanopositioning over large travel and the negative effects of hysteresis characteristics and external disturbances. An integral back-stepping linear active disturbance rejection control (IB-LADRC) strategy is introduced in the scanning mode, which uses a linear extended state observer to estimate displacement, velocity, and total disturbance in real time. Simulation and experimental results demonstrate that the IB-LADRC algorithm effectively improves the positioning accuracy of the PSSNS system.

Summary: This article proposes a novel robust adaptive piecewise indirect inverse output-feedback control scheme to mitigate butterfly-like hysteresis with creep in smart material actuators. Piecewise indirect inverse indicates that it is not a true hysteresis and creep inverse compensator, but an online decoupling mechanism to accessing the approximately actual control signal from the designed hysteretic and creeping temporary control signal. In addition, a new butterfly-like relay operator is proposed for the first time, leading to the construction of a new model of butterfly-like hysteresis with creep. Finally, the experimental results on the dielectric elastomer actuator motion control platform illustrate the effectiveness of the proposed output-feedback control scheme.

Summary: This article proposes an adaptive pseudoinverse control scheme based on fuzzy logic system (FLS) and barrier Lyapunov function (BLF) for a class of state-constrained hysteretic nonlinear systems. The hysteresis nonlinearity in the actuators is considered and mitigated by the proposed pseudoinverse control algorithms. The all-state-constrained control problem of the Preisach hysteresis model is overcome with the aid of an FLS, BLFs, and the proposed hysteresis pseudoinverse algorithms.

Summary: Piezoelectric hysteresis is a critical issue affecting the motion accuracy of piezo-actuated nanopositioners, and this article proposes a novel method based on a polynomial-based fractional order disturbance model to address this challenge. The method does not require expensive computational resources and can be easily implemented in an analog manner, offering advantages of high bandwidth and low cost. Extensive modeling and tracking experiments demonstrate the effectiveness of the proposed method in significantly suppressing piezoelectric hysteresis nonlinearity over a wide bandwidth.

Summary: This study proposes a new mathematical model that accurately describes the hysteresis nonlinearity of piezoelectric ceramics. The model simplifies the hysteresis main loop using high-order rational fractions and utilizes a recursive algorithm for hysteresis segmentation. Simulations and experiments demonstrate the successful modeling of the hysteresis characteristics between input voltages and output displacements. The proposed model lays the foundation for subsequent control of piezoelectric ceramic actuators and improves the positioning accuracy of ultraprecision motion systems.

Summary: This paper presents the design of a 3DOF XYZ bi-directional motion platform based on Z-shaped flexure hinges. Bridge-type mechanisms and Z-shaped flexure hinges are used to amplify the output displacement. Bi-directional motion along the X-axis and Y-axis is achieved using the famous differential moving principle DMP, while bi-directional motion along the Z-axis is realized by the reverse arrangement of the Z-shaped flexure hinges. Statics and dynamics analyses are conducted, and simulations are carried out to demonstrate the effectiveness of the design. The results show that the platform has average displacements of ±125.58 μm, ±126.37 μm, and ±568.45 μm in the XYZ-axis, respectively.
