The software allows you to perform the following tasks:

  • Control of thyristor converters
  • Control coordinates the drive (regulation current of anchor chain, regulation of voltage (EMF, speed, power, position), regulation current of excitation)
  • Support of the speed reference system (intensity, push)
  • Linearization of the dynamic characteristics of the current loop in the control range and exclusion of undesirable processes in control loops
  • Function PLC for technological process control

Implementation of the software for the controller control system «Proton» is carried out by using the embedded application tool EAT-Eclipse. In the project is necessary to make the scheme of the functional blocks and binding them to the hardware controller.

EAT-Eclipse have high level domain-specific graphical user interface, programming skills no need. Based on the model source code will be generated automatically.
