The article deals with the problem of modeling an automated control system for the process of electroplating metal parts. The analysis of literature sources devoted to electroplating is carried out. The problem and process of electroplating metal parts with the use of reverse is considered. The calculated ratios are given to determine the required current (direct, reverse, increased, reversed), the process time and other internal parameters for the galvanization process. The possibility of performing current switching, setting its value and determining the process time, as well as reversing with the help of automation tools is considered on the example of the model. The model allows for given geometrical parameters galvanization details and preset thickness of the plating to calculate the basic control parameters of galvanization process: electroplating current and duration of the electroplating process. The electroplating process model is sensitive to the shape of the electroplated parts and the composition of the electrolyte, so the automated control system must perform model calculations for each type of parts and electrolyte. Graphs of simulation results in the SimInTech software environment obtained by drawing up a block diagram for a model of an automated control system for the process of galvanizing parts are presented.

The article considers the solution of the problem of distributed control of a group of stepper motors based on multi-channel transceivers. The analysis of literature sources devoted to the development of wireless stepper motor control systems is carried out. The expediency and possibility of distributed control of stepper motors of manipulator links using multi-channel transceivers are considered. It is assumed that there is a need for two-way information exchange between the stepper motor module and the Central control system. The design ratio for the duration of the cycle of the full package of control information with the values of the duration of pauses, switching reception and transmission, the duration of the preamble and the duration of transmission of the address, useful information and checksums of the package. The possibility of increasing the maximum frequency of control pulses transmitted over the information channel when transmitting a sequence of control packets instead of single packets is proved. The structure of the package for controlling the electronic stepper motor driver is defined, including a pointer to the direction of rotation, the duration of pulses and the degree of fractional step. An example of calculation, based on the obtained ratios, of the maximum speed of rotation of the stepper motor shaft for specific models of the engine and the transceiver in the case of a six-channel control system is given. Keywords: distributed control, stepper motor group, control package, frequency of control pulses.
