Vector–controlled AC servo drives, providing previously unattainable performance indicators for controlling various objects, are a basic part of modern precision automated equipment. They are complex technical devices, the further improvement of which goes in the direction of increasing their intelligence and universatility. The article analyzes the structural peculiarities and settings of domestic servo drives with vector control of the types of SPS and SPSh, ensuring the effective use of their wide functional capabilities. The rules and procedure for setting the digital PID controller in the subordinate regulation system using the hardware and software of the servo drives are determinated. This ensures the optimisation of the process of controlling the movement of actuators.

Solving the problem of FNC interaction within a distributed control system requires an analysis of the nature of technological processes, analysis of the dependence of FNC algorithms on data or control, etc. This analysis makes it possible to identify the features of the FNC organization from the point of view of control and communication requirements for solving the task. The article analyzes the development trends of industrial network ecosystems, software and hardware tools for the implementation of network associations participants. In particular, the considered capabilities of the software platform based on the IEC 61499 standard for the development of FNC control programs meet the requirements for network components. Possible non-determinism of interaction (as noted in [9]) is proposed to be compensated by using FPGAs as part of FNC controllers when creating additional fast communication links for the implementation of deterministic network applications. The proposed additional FPGA-based computing platform together with the ARM controller forms a hybrid computer as part of the FNC, which allows you to control fast technological processes. A multi-level configuration of an industrial network with the unification of individual FNCs into clusters is proposed and substantiated. This configuration allows you to flexibly combine the boot and communication tasks of FNC, if necessary, performing the exchange of information between clusters. The developed model in the AnyLogic 8.6 software package showed the effectiveness of the proposed configuration. The results of the experiments led to the conclusion that an increase in the intensity of messages has a greater effect on work efficiency than an increase in the number of FNCs. The development of this topic is expected in the following areas: improving the characteristics of FNC in terms of computing and communication capabilities. Development of an algorithm for optimizing the message transmission path between clusters, with an analysis of the waiting time of busy DS-links.
