The possibilities of using automatic control theory in problems of assessing the dynamic condition of technical objects are assessed. The structural diagram of a mechanical oscillatory system with a solid body on elastic supports is considered. The system performs vibration movements created using a monoharmonic signal. The signal is generated by an inertial vibrator, which provides stable vibrations of the working body of a technical object in external excitation mode. The source of a monoharmonic signal has the ability to move along the length of the working body of a technical object to create the necessary dynamic conditions. Setting the dynamic state of a technical object can be done manually, for which data on the vibration parameters of the working body obtained from vibration sensors installed at the ends of the working table of the technical object are used. The automatic operating mode involves the use of a system for monitoring the dynamic condition of a technical object using an automatic control system, which includes vibration sensors, an information processing unit, a software device and an appropriate communications system. A method is proposed for controlling the dynamic condition of a technical object, aimed at implementing the processes of interaction of bulk granular media with the surfaces of parts by maintaining and adjusting the structure of the vibration field, which is formed by the corresponding plane vibrations of the working fluid (vibration platform) in the form of a solid body, caused by vibration movements of vibration exciters (or vibrators) ), the management of which creates the necessary conditions for the implementation of the technological process. The proposed approach relates to the scientific and technical areas of the theory of control of technical systems and is associated with the assessment, control and formation of dynamic condition of technical objects under conditions of intense vibration processes affecting technical objects.
