“…However, the analysis of existing 2 RS Global methods, which is given in [8], allowed to identify shortcomings that prevent their widespread use, namely insufficient reliability, high cost, sensitivity to errors in determining the parameters of the oscillating system, the possibility of using only to VM start with self-synchronizing, unconnected among themselves unbalance vibrating exciters, lack of control exit to the resonance mode. In the writings [8,9], to reduce the amplitude of oscillations of VM actuating device during passing the resonance zone, it is offered the use of a frequency-controlled electric drive. This solution allows turning off the possible "jamming" of the drive motors rotors and reduces the dynamic loads on VM structural elements when using motors with the power required operating in the technological operating mode.…”

The above resonance vibration machines are widely used in various industries, but have a number of shortcomings associated with increasing of the oscillations amplitude when passing the resonance zone during start-up. It is noted that to reduce the oscillations amplitude and quickly pass the resonance zone, it is advisable to use a frequency-controlled electric drive with the formation of additional control effects. Features of frequency start of the electric drive of the vibration machines are noted. The structure of the electric drive control system during passing the resonance zone in the process of starting the above resonance vibration machine in the form of a block-scheme is proposed. The algorithm of operation of the control system is given.

“…At present, there are practically no studies in the field of ensuring the synchronous operation of the mechanisms of vibration machines by means of a closed-loop controlled electric drive, the synthesis of regulators, and the search for the boundaries of the stability of the synchronous mode, without which it is impossible to create highly efficient vibration machines. References [ 15 , 16 ] are devoted to the study of the possibility of using a closed-loop adjustable electric drive to ensure the synchronous rotation of unbalances; however, the problems of passing the resonance zone and controlling the relative position of the unbalances and compensating torques when the axes of rotation of the unbalances do not receive proper further development.…”

In European industry, such as metallurgical, mining and processing, construction, food, and chemical, vibration exciters are used, which indicates their wide and, in some cases, unique technological capabilities. The most common are electromagnetic and unbalanced vibration exciters. The advantages of electromagnetic vibration exciters include the ability to control the amplitude of the vibration by changing the electrical power supplied; the disadvantages are high material consumption. However, unbalanced vibration exciters have low energy efficiency, which is associated with difficult start-up conditions and with an overestimated mechanical power of the vibration exciter in relation to the power required by the technology itself, which is due to the need to minimize the effect of the technological load on the operating mode of the vibrating unit. Adjusting the amplitude of the disturbing force of unbalanced vibration exciters, regardless of the vibration frequency, will make it possible to reduce the installed power of the unit by passing the resonant frequency with a minimum disturbing force and compensating for the effect of the process load by means of a closed-loop electric drive. In the course of the study, an analytical description of the interaction of the rotating unbalances located on a common movable platform was obtained. On the basis of these analytical dependencies, a mathematical model was developed that takes into account the dynamic characteristics of a frequency-controlled asynchronous electric drive of a closed-loop control system for the mutual arrangement of rotating unbalances. The simulation results confirmed the possibility of using the specified electric drive to control the oscillation amplitude directly in the process of operation of a four-unbalanced vibration exciter. A physical experiment was carried out to determine the transient processes of changing the angular velocity of an induction motor with an abrupt change in the frequency converter setting. On the basis of this experiment, the previously created mathematical model was refined in terms of describing the dynamic parameters of the electric drive. The proposed structure of the control system, the performance of which has been confirmed by mathematical modeling, makes it possible to implement an adjustable four-unbalanced vibration exciter using single commercially available asynchronous vibrators.
