Digital control systems for electrical systems

Lecturer: Ph.D., Associate Professor Bosak Alla Vasylivna

The purpose of studying the discipline – the formation of the student’s theoretical and practical knowledge of building digital models of electromechanical systems and creating effective control algorithms for their study in practice. The study of the material of this discipline is focused on the widespread use of computer technology.
The subject of the discipline is digital control systems for electrical systems.
The result of studying the discipline is the formation of students’ abilities:

  • ability to provide modeling of electrotechnical and electromechanical objects and technological processes of production, transmission and distribution of electric energy with use of standard packages and means of automation of engineering calculations, to carry out experiments according to the set techniques with processing and the analysis of results;
  • ability to identify, classify and describe the operation of systems and components through the use of analytical methods and modeling methods;
  • ability to demonstrate knowledge and skills in conducting experiments, data collection and modeling in electrical, electrical and electromechanical systems.

The discipline “Digital control systems of electrical systems” consists of 3 sections:

  • Section 1. Introduction to the course “Digital control systems of electrical systems”:
    Topic 1.1. Theoretical bases of construction of digital control systems.
    Topic 1.2. Sampling of continuous systems based on Z-transform and Z-forms.
  • Section 2. Digital control of dynamic objects:
    Topic 2.1. Digital control of open and closed systems.
    Topic 2.2. Implementation of digital regulators.
  • Section 3. Optimization of dynamic modes of the CSB:
    Topic 3.1. Use of delayed links and standard controllers in optimal control systems.
    Topic 3.2. Digital control of the electric drive.
