“…24,25 The mechanical properties of the leaf spring system have been analyzed in many applications. 26 However, the application of the leaf spring system as the main vibration element in vibration screen has rarely been reported. Moreover, the dynamic characteristics of the leaf spring system in vibration screen have not been researched.…”

By studying dynamic characteristics of the leaf spring system, a new elastic component is designed to reduce the working load and to a certain extent to ensure the linearity as well as increase the amplitude in the vertical and horizontal directions in vibration screen. The modal parameters, amplitudes, and amplification factors of the leaf spring system are studied by simulation and experiment. The modal results show that the leaf spring system vibrates in horizontal and vertical directions in first and second mode shapes, respectively. It is conducive to loosening and moving the particles on the vibration screen. In addition, it is found that the maximum amplitude and amplification factor in the horizontal direction appear at 300 r/min (5 Hz) while those in the vertical direction appear at 480 r/min (8 Hz), which are higher than those in the disc spring system. Moreover, the amplitude of the leaf spring system increases proportionally with the increase of exciting force while the amplification factors are basically the same under different exciting forces, indicating the good linearity of the leaf spring system. Furthermore, the minimum exciting force occurs in the leaf spring system under the same amplitude by comparing the exciting force among different elastic components. The above works can provide guidance for the industrial production in vibration screen.

“…In order to keep in step with the rapid development of the auto industry, we study an adaptive eventtriggered control problem for the magnetic levitation ball-type systems. Compared with the existing works, the main innovations of this paper can be summarized as follows: (a) The event-triggered control algorithm has been applied in automobile suspension control by Li et al (2019), Liu and Li (2020) and Ding et al (2021). In Wang et al (2021), the investigated fuzzy-based adaptive event-triggered nonlinear systems within fixed-time interval, but it emphasizes on theoretical research.…”

In this article, an adaptive event-triggered control scheme is first investigated for new type tyre systems based on vehicle. The intricate systems are transformed into a nonlinear model to research. The improved event-triggered mechanism (ETM) is proposed to enhance effectively the data transmission capacity of the systems and reduce the communication bandwidth. For the sake of conquering the problem of 'explosion of complexity' in traditional adaptive backstepping recursive design process, the dynamic surface control (DSC) technique is introduced in control design process. Based on the Lyapunov stability theory, the developed control scheme guarantees all the variables in the closed-loop system are semi-globally uniformly ultimately bounded (SGUUB). Finally, the simulation results verify the rationality and effectiveness of the proposed control scheme.

“…Existing papers directly use the time-delay systems theory when solving the consensus problem of MASs with time delays, and it will make MASs accept time delays passively and conservatively. On the contrary, the networked predictive control is used to compensate for the effects of time delays, and it has been successfully used to networked control systems [41], [42]. To compensate the communication delay actively, the networked predictive scheme(NPS) is employed in this paper.…”

In this paper, the problem of group leader-following consensus is discussed for high-order heterogeneous multi-agent systems(HMASs) with multiple leaders and time delays. The four situations are considered: autonomous leaders, active leaders with controllers, and accepting their own information with/without time delays. Different protocols are designed for different situations. Under the corresponding protocols, HMASs can achieve group leader-following consensus without the limitation of in-degree balance. And the networked predictive scheme(NPS) actively compensating for time delays is used to predict current information of agents. Besides, the results are extended to multiple groups case. Finally, the simulation results show that, based on the NPS, the state trajectory of each agent in the time-delay case is very close to that in no time-delay case.
