Improving the performance of technological operations is an urgent task of modern science. Vibrational equipment is one of the common types of industrial equipment used for operations such as sieving, crushing, vibration conveying, etc. An energy-based approach to controlling vibration units allows maintaining a constant level of the total oscillation energy of the vibration unit with a load, which opens up wide opportunities for intellectualizing equipment control under conditions of parameter space uncertainty. This work aims to study the influence of the completeness of information about the vibrational state of the system on the performance of the speed gradient algorithm when controlling multiple synchronization of rotors of a vibration unit. The paper presents results of numerical simulation based on the system dynamics equations and approximate values of the vibration unit parameters. Results of experimental studies on the mechatronic vibration setup SV-2M are presented.
