“…Piezoelectric actuators (PZAs) have been widely used in various ultra-precision cutting technologies, such as ultrasonic vibration cutting [ 1 , 2 ], fast tool servo technology (FTS) [ 3 ], ultra-precision cutting technology [ 4 ] and even machining vibration detection [ 5 ], due to their high positioning resolution, small size and quick response [ 6 , 7 , 8 ]. Especially with the rapid development of three-dimensional elliptical vibration cutting (3D-EVC) [ 9 , 10 ] in the past few years, 3D-EVC not only has the advantages of restraining tool wear, restraining tool brittleness and obtaining excellent machining quality, but also has obtained higher machining efficiency.…”

The piezoelectric actuator has been widely used in modern precision cutting technology due to its fast response speed and high positioning accuracy. In recent years, with the development of precision technology, modern cutting requires higher and higher cutting accuracy and efficiency. Therefore, this paper proposes a feedforward control method based on the modified Bouc–Wen (MBW) model. Firstly, a novel asymmetrical modified Bouc–Wen model with an innovative form of shape control function is developed to model the hysteresis nonlinearity property of piezoelectric actuators. Then, a self-adaptive cooperative particle swarm optimization (PSO) algorithm is developed to identify the parameters of MBW model. The comparative evaluation reveals that the MBW model outperforms the classical Bouc–Wen (CBW) model by 66.4% in modeling accuracy. Compared with traditional PSO algorithm, the self-adaptive cooperative PSO algorithm can obtain minimum fitness in parameter identification. Furthermore, the feedforward control strategy is realized to improve the position tracking accuracy. A position tracking experiment verifies that the feedforward control strategy improves the tracking accuracy of piezoelectric actuators significantly compared with the open-loop control strategy.

“…Using the inverse piezoelectric effect of piezoelectric materials, various piezoelectric actuators have been developed to meet the requirements of precision positioning. To achieve large-stroke movement, several stepping piezoelectric driving principles have been proposed, which can be classified by the working principles of inchworm actuators [6,7], stick-slip actuators [8,9], impact actuators [10,11], ultrasound actuators [12,13], and so on. Compared with other types of actuators, stick-slip piezoelectric actuators have the advantages of simple structure and convenient control; therefore, they have been widely investigated in recent years.…”

A Novel Rotation-Structure Based Stick-Slip Piezoelectric Actuator with High Consistency in Forward and Reverse Motions

Under the same driving voltage and frequency, the forward and reverse motion inconsistency of stick-slip piezoelectric actuators would bring difficulty for subsequent control. To solve this problem, a rotation-structure based piezoelectric actuator with completely symmetric structure and two driving feet was initially proposed. By testing its output performances under various driving voltages and frequencies, it was confirmed that, although similar speeds could be achieved for forward and reverse motions, the maximum displacement and backward displacement in each step were still quite different. By analyzing the reasons leading to this difference, this actuator was further improved by using only one driving foot. The experimental results showed that the forward and reverse motion consistency of the improved actuator had been significantly improved. The deviation rate was only 1.6%, corresponding to a travel distance of 118.7 μm, obtained under the driving voltage of 100 V and driving frequency of 10 Hz. The comparison with some previously reported actuators further confirmed the advancement of this improved actuator.

“…Sci. 2020, 10, 6682 2 of 12 type piezoelectric actuators utilize single vibration mode or coupling of multi vibration modes to generate micro amplitude elliptical motion of their driving foot, and then the macro motion can be achieved due to the friction coupling effect [16,17]. This accumulation of micro-movement enabled resonant piezoelectric actuators to function with higher output velocity and more considerable movement travel.…”

Utilizing the inherent advantages of the piezoelectric driving technology, such as good adaptability to vacuum environment and no electromagnetic interference, a novel self-moving framed piezoelectric actuator is proposed, simulated, and tested in this study, holding a potential application for magnetic confinement fusion. Four piezoelectric composite beams form a framed piezoelectric actuator. Two orthogonal vibration modes are excited and coupled in the framed piezoelectric actuator, producing a microscopic elliptical motion at its driving feet. Due to the friction, the framed piezoelectric actuator can move on a rail, thereby constructing the railed carrying system. Numerical simulation is carried out to confirm the operation principle and to conduct the dimensional optimization of the proposed framed piezoelectric actuator. A prototype of the proposed framed piezoelectric actuator with a weight of 83.8 g is manufactured, assembled, and tested, to verify the piezoelectric actuation concept. The optimal driving frequency of 20.75 kHz is obtained for the proposed actuator prototype, and at the excitation voltage of 400 Vpp its maximum mean velocity of 384.9 mm/s is measured. Additionally, the maximum load weight to self-weight of the proposed actuator prototype reached up to 10.74 at the excitation voltage of 300 Vpp. These experimental results validate the feasibility of the piezoelectric actuation concept on the railed carrying system.
