The article presents the need to create an imitation model for the regulation of the intensifying oscillations during the transition processes in the mechanical part of an asynchronous electrical drive system operated with percussive load. The purpose of the scientific article is formulated, which is to develop a model for regulating the mechanical part of an asynchronous electrical drive operating with a percussive load, in which the possible random changes in the resistance torque of the technological mechanism are taken into account. The presented goal has been implemented in two stages. The torque of percussive load of the technological mechanism is modeled. For this purpose, approximations of step functions and their linear combinations by smooth functions are considered. Using the approximation function of the percussive load torque, a model for regulation of the mechanical part of the electrical drive system has been developed in the Simulink environment of the Matlab software package. The results obtained have been tested on the example of the "Ore crusher-asynchronous electric motor" system. A comparative analysis of the operating characteristics of models of the mechanical part of the electrical drive system, operating with percussive load without the PID regulator and the one with a regulator has been carried out. The results obtained show that due to the introduction of the PID regulator into the mechanical part of electrical drive system, operating with the percussive load, the duration of oscillations attenuation in transients is reduced, which can prevent premature deformation of the mechanical links.
