“…This section presents the simulation results for the relative-degree-one case of a noncanonical nonlinear approximation system (6) with unknown parameters and preceded by the Preisach hysteresis operator. The purpose of this section is to provide strong evidence for the proposed adaptive control scheme in achieving the desired tracking performance, as illustrated in Theorem 1, which guarantees that the tracking error converges to zero as time tends to infinity.…”

“…Hysteresis widely occurs in smart material-based actuators [1][2][3], such as electromagnetic actuators [4] and piezoelectric actuators [5]. Experiments show that the system with hysteresis would exhibit poor tracking performance when the feedback control does not explicitly consider hysteresis [6]. To compensate for the hysteresis nonlinearity in control design, a mathematical operator that can describe the characteristics of the hysteresis nonlinearity is needed.…”

To describe the hysteresis nonlinearities in smart actuators, numerous models have been presented in the literature, among which the Preisach operator is the most effective due to its capability to capture multi-loop or sophisticated hysteresis curves. When such an operator is coupled with uncertain nonlinear dynamics, especially in noncanonical form, it is a challenging problem to develop techniques to cancel out the hysteresis effects and, at the same time, achieve asymptotic tracking performance. To address this problem, in this paper, we investigate the problem of iterative inverse-based adaptive control for uncertain noncanonical nonlinear systems with unknown input Preisach hysteresis, and a new adaptive version of the closest-match algorithm is proposed to compensate for the Preisach hysteresis. With our scheme, the stability and convergence of the closed-loop system can be established. The effectiveness of the proposed control scheme is illustrated through simulation and experimental results.

“…Herein, as an important index, the flow rate of the EHA depends on the stroke and operating frequency of the smart material actuator. Although the bandwidth of some smart material actuators can reach several thousand Hz [19,20], the output displacement can only reach one to two thousandths of their length [21]. As a result, the output flow of EHA driven by smart materials is relatively low to meet the requirements of practical applications.…”

Smart materials-based electro-hydrostatic actuator (EHA) plays an important role in the power-by-wire technology for the next generation of more electric aircraft. However, the output flow of a smart materials-based EHA is relatively low to narrow down its practical applications. To address this issue, a piezoelectric material-based dual-mode electrohydrostatic actuator (DMEHA) is proposed in this work. The output flow can be improved by adopting two piezoelectric pumps without sacrificing the carrying capacity. In addition, a hybrid serial and parallel configuration for the two pumps is realized for the adaptability of different actuation requirements. Mathematical modeling and parameter identification are conducted and presented in detail for the designers. A physical prototype is fabricated and a series of experiments are carried out to investigate its characteristics. Results indicated that the DMEHA achieves a maximum output flow of 1.17 L/min at 360 Hz under the serial mode and the blocking load up to 40 kg. The corresponding maximum output flow in the parallel mode can reach 1.96 L/min at 420 Hz, and the blocking load is 20 kg.

“…Magnetostriction refers to the alteration in length or volume of ferromagnetic materials when they are magnetized in an external magnetic field [1][2][3][4][5]. Materials with excellent magnetostrictive properties hold significant potential for various applications including sensors, brakes, micro-electro-mechanical systems, energy harvesting, and underwater sonar scanning [6][7][8][9][10]. Magnetostrictive materials, including Fe [11][12][13][14][15], Terfenol-D (terbium dysprosium iron alloy) [16], and Fe-Ga alloy [17,18], have been widely studied.…”

Defects are an inevitable occurrence during the manufacturing and use of ferromagnetic materials, making it crucial to study the microscopic mechanism of magnetostrictive properties of ferromagnetic materials with defects. This paper conducts molecular dynamics simulations on low-dimensional iron thin films containing hole or crack defects, analyzes and compares the impact of defect size on magnetostrictive properties, and investigates the microscopic mechanism of their effects. The results indicate that the saturation magnetostrictive strains of the defect models do not increase monotonically as the defect size increases. Additionally, it is discovered that the arrangement of atomic magnetic moments in the initial magnetic moment configuration also affects the magnetostrictive properties. When controlling the size of the hole or crack within a certain defect area, it is found that the hole size has less influence on the initial magnetic moment configuration, resulting in a smaller corresponding change in the saturation strain and thus having a lesser impact on the magnetostrictive properties. Conversely, when the crack size changes, the arrangement of the atomic magnetic moments in the initial magnetic moment configuration changes more significantly, resulting in a greater corresponding change in saturation strain, and thus having a greater impact on the magnetostriction performance.
