“…However, this way of controlling the system has its own drawbacks, since the control unit is quite complex, requiring a large number of sensors that transmit information to the PLC. Therefore, the system breaks down faster and its maintenance becomes expensive [2,3,[20][21][22][23]. Feedbackbased control of vibratory dosing systems is widely used in practice.…”

In the industrial and sales processes, dosing systems of various constructions, whose operation is based on mechanical vibrations (vibratory feeders), are very often used. These systems face many problems, such as resonant frequency, flow instability of dosed product, instability of mechanical vibration amplitude, etc., because most of them are based on controlling the frequency of the electrical signal of the supply voltage. All these factors negatively affect the durability and reliability of the vibratory feeder systems. During this research, an automatic control system for vibratory feeder was created, whose control process is based on the modification of the sinusoidal signal (partially changing the signal area). In addition, such a way of controlling the vibratory feeder is not discussed in the literature. As the research conducted in this paper has shown, while using sinusoidal signal modification it was possible to achieve a stable flow rate of bulk production (the flow rate varied from 0 to 100 g/s when the frequency of mechanical vibrations changed from 1 to 50 Hz) and a stable amplitude of mechanical oscillations was achieved and equal to 1.5 mm. The control system is based on the microcontroller PIC24FV32KA302 for which the special software was developed. The thyristor BTA16 used for voltage modification of the sinusoidal signal made it possible to ensure the reliable control of the sinusoidal voltage modification process.

“…Aiming at the dual linear motor system, Lin et al 18 apply intelligent complementary sliding mode controlling method to implement cross-coupled synchronous. Attention to different frequency of motors in the synchronization motion, Jia et al 19 , 20 propose the adaptive fuzzy PID method and realize the multifrequency controlled synchronization motion. Tian et al 21 illustrate the fast and robust estimation for positions and velocities by using a generalized modulating functions method.…”

In this article, multifrequency controlled synchronization of four inductor motors by the fixed frequency ratio method in a vibration system is investigated. The electromechanical coupling dynamical model of the vibrating system is established. The synchronous condition of the vibrating system is obtained with the small parameter method. Through the theoretical derivation and numerical simulation, multifrequency self-synchronization of four induction motors in the vibration system can’t be realized. To achieve the purpose of multifrequency synchronization motion, the method of multifrequency controlled synchronization is proposed, and a fuzzy PID controlling method is introduced. The stability of the controlling system is certified by the Lyapunov criterion. An arbitrariness of the proposed controlling method which is applied to the vibration system is presented. To certify the accuracy of the theory and simulation, a vibrating test bench is constructed. Some experiments are operated to validate the effectiveness and the proposed controlled synchronization method.

“…From the recently published works concerning the synchronization of vibrators (Chen et al, 2016; Cieplok and Wojcik, 2020; Lyan et al, 2021; Zhang 2020; Zhang et al, 2020, 2021; Zhao et al, 2010), the dynamic model become more closely related to the actual vibrating machines including vibrating conveyor, vibrating screen, and vibrating mill, and so on. Besides, although the control synchronization (Fang et al, 2021; Fradkov et al, 2021; Huang et al, 2021; Jia et al, 2019; Li et al, 2022), multiple-frequency synchronization (Li and Chen, 2019; Zou et al, 2021), and composite synchronization (Kong and Wen, 2018) have also been investigated, the self-synchronization theory was still the most typical synchronization strategy used in engineering. With the development of synchronization theory, some scholars also paid attentions to other problems in designing vibrating machines, such as dynamic adjustment of vibration direction angle for the vibrating screen (Chen et al, 2020), and two-stage vibration isolation of vibratory shake-out conveyor (Fiebig and Wrobel, 2017).…”

Due to complex dynamic coupling relationships in the system, the research that couples pendulum and vibrators in the same system is rarely found. Especially in the vibrating system with spatial motion, the theoretical derivation may be too complex to be easy to implement. In this paper, we present a vibrator-pendulum coupling system with spatial motion characteristics; here, the pendulum is driven by the two vibrators mounted on it. The synchronization of the vibrators and the motion characteristics of the system are studied via theory, numeric, and experiment. In theory, the synchronization and stability criteria of the two vibrators are deduced. According to the theoretical results, some numerical qualitative analyses are given to further reveal the synchronous stable states and spatial motion characteristics of the system. The validity of the theoretical methods and the correctness of the numerical qualitative results are examined by simulation and experiment. Taking the pendulum as the working rigid frame, the proposed dynamic model and research results can be applied to design a new kind of vibrating jaw crusher with spatial motion characteristics.
