“…FNN not only can automatically generate the universe and control rules of fuzzy variables by training but also has the ability to handle fuzzy information, which can avoid the absence of control accuracy due to the lack of control experience of designers. [28][29][30][31] Based on the test of TFC35 electric forklift, VSR control scheme based on FNN is designed. The inputs are the velocity and the hand-wheel angle, and the output is steering ratio.…”

For the TFC35 steer-by-wire forklift, a linear 3-degree-of-freedom forklift model is given, which provides a verification model for variable steering ratio design. The concept of ideal steering ratio is expounded. The variable steering ratio algorithm based on constant yaw rate gain and the variable steering ratio algorithm based on constant lateral acceleration gain are studied. A variable steering ratio algorithm based on two kinds of gain combination is proposed. The advantages and disadvantages of the above three static variable steering ratio algorithms based on constant gain are simulated and analyzed. Aiming at complex working conditions, a dynamic variable steering ratio control scheme based on fuzzy neural network is proposed. The definition, implementation steps, and adjustment algorithms of each layer of fuzzy neural network are given. The final experiment results show that the dynamic variable steering ratio method based on fuzzy neural network is more resistant to the disturbance of its own parameters and can be used in complex dynamic conditions, which helps to improve the handling stability of the forklift.

A model of photovoltaic-electrostatic cantilever beam based on lanthanum-modified lead zirconate titanate ceramic is proposed in this article. New equivalent electrical model of lanthanum-modified lead zirconate titanate ceramic connected to a parallel plate composed of two copper foils is obtained by modifying the original lanthanum-modified lead zirconate titanate equivalent electrical model. After that, the mathematical model of photovoltaic-electrostatic cantilever beam is established. Furthermore, the influences of ultraviolet light intensity and copper foil length on the deflection of the photovoltaic-electrostatic cantilever beam are analyzed via the theoretical and experimental methods. The analysis results indicate that the deflection at the free end of cantilever beam increases with the increase in light intensity and length of the copper foil. The photovoltaic-electrostatic flexible cantilever beam can be taken as a micro-actuator with the advantages of remote control and clean drive.

“…Poosanaas-Burke et al (2000) pointed out that the optical second-order nonlinear effect mainly leads to the photovoltaic electric field using the voltage source model, and then proposed a mathematical model without time parameter. Based on the above-mentioned constitutive equations, many scholars have researched the active vibration control and shape of photostrictive laminated flexible structures (Rahman and Nawaz, 2011; Zheng, 2012), beams (Sun and Tong, 2008; Yue et al, 2014; Zheng et al, 2014), plates (Luo and Tong, 2011), and shells (He and Zheng, 2014; Jiang et al, 2013; Shih et al, 2004, 2009; Wang et al, 2011). However, the response of photodeformation is far slower than the photovoltage, which was experimentally discovered by Saitoh and Kametani (1996) and also investigated by Huang et al (2015b).…”

A photovoltage closed-loop servo control model of lead lanthanum zirconate titanate ceramic is proposed for a photovoltaic-electrostatic-driven system in this article. The control equations of the proposed servo control model are derived based on the mathematical model of lead lanthanum zirconate titanate with coupled multi-physics fields. The parameters of photovoltage of lead lanthanum zirconate titanate ceramic during the illumination phase and light-off phase are identified through the static experiment. Then, photovoltage response of lead lanthanum zirconate titanate ceramic with simple on–off control strategy is numerically simulated based on the control equations presented in this article. After that, the closed-loop photovoltage control experiment based on single lead lanthanum zirconate titanate ceramic is carried out. The simulation and experimental results show that the photovoltage can be successfully controlled by switching the ultraviolet light with an optical shutter. The control strategy can be applied in the photovoltaic-electrostatic-driven servo system to achieve the target degree of angular or displacement deflection. In addition, closed-loop photovoltage control experiment of lead lanthanum zirconate titanate bimorph irradiated by double ultraviolet light is carried out to equip the system with the capacity of reverse voltage output.
