SYNTHESIS OF DIGITAL CONTROL SYSTEM OF THE LOW-FREQUENCY ELECTRODYNAMIC ACTIVATOR OF VIBRATIONS
In article the principle of operation of the low-frequency electrodynamicactivator of vibrations and relevance of expansion of frequency range of device taking with equipment development is described. The discrete mathematical model of the activator of vibrations is considered, transfer function of object of management is defined. The stability analysis is carried out. The function chart of a digital control system of the activator of vibrations is constructed, synthesis of the discrete regulator is carried out. Technical realization of a digital control system of the low-frequency electrodynamicactivator of vibrations is considered, the description of the developed system is provided. The software structure is given in article for digital system. System tests on the operating device showed that at frequencies of fluctuations of 0,2 - 0,4 Hz there are the resonant phenomena caused by imposing of frequency of the regulator on own frequency of object of management.This problem is solved by introduction in algorithm of the digital regulator of the correcting amplitude coefficient depending on the setting frequency.
