Stroke maximizing and high efficient hysteresis hybrid modeling for a rhombic piezoelectric actuator

Kinetostatic and Dynamic Modeling of Flexure-Based Compliant Mechanisms: A Survey

“…Ma et al [77] derived the analytical formula of the displacement amplification ratio for bridge-type compliant mechanisms based on elastic beam theory. Subsequently, plenty of similar analytical formulas sprung up, such as those by Mottard and St-Amant [183], Hwang et al [184], Xu and Li [185], Chen et al [79], Shao et al [186], Liu and Yan [187], and Higuchi and Higuchi [188]. In view of the low prediction accuracy of some previous models, Qi et al [78] and Ling et al [80] separately proposed enhanced analytical formulas based on elastic beam theory.…”

On hysteresis modeling of a piezoelectric precise positioning system under variable temperature

“…For example, these applications include the Atomic Force Microscopy (AFM) [2,3], manipulator applications [4,5,6], piezoelectrically actuated hydraulic valves [7], diesel injectors [8], medical microrobots [9]. Different hysteresis models have been used to characterize the voltage-to-displacement hysteresis nonlinearities in piezoelectric material-based actuators over different operating conditions have been presented in a number of recent studies, see for example [10,11,12,13,14]. In [10], the both rate-independent and rate-dependent hysteresis in piezoelectric actuators were modeled using a Takagi-Sugeno fuzzy system.…”

Design and Analysis of a Novel Piezo-Actuated XYθz Micropositioning Mechanism with Large Travel and Kinematic Decoupling

“…Zhu et al presented a redundantly piezo-driven XYθ z compliant mechanism with high dynamic characteristics but working ranges in X, Y, and θ z directions of merely 12.42 μm, 24.82 μm, and 1.75 mrad, respectively [12]. To increase motion ranges, bridge-type amplification mechanisms are used for amplification of the deformation of piezoelectric materials because of their compact structure and high displacement amplifying ratio [13][14][15][16][17]. Although an existing XYθ z micropositioning system having an amplification mechanism has larger working ranges, it employs larger stack-type actuators, which increase the system size [18].…”
