Course abstract

Automation - a branch of science and technology that covers the theory, practice and design principles of automated control systems. It consists of automation technical means and automation control theory. The study program prepares highly qualified, competitive and competent specialists for the analysis, control, regulation and management of food automated technological processes (TP) in accordance with the requirements of automated industrial engineering. During the study process, students acquire knowledge, skills and competencies that correspond to the paradigms of modern engineering and management science. During the study process, students get acquainted with the principles of computer control of food production TA, learn the principles of TP quality and efficiency evaluation and management, which include the methods used by the world's leading industrial companies.

Learning outcomes and their assessment

Knowledge - the student knows the elements of automation and their application in food production, technological processes and the specifics of production automation, methods of analysis, synthesis, design and calculation of automation equipment and processes - lectures and theoretical test.

Skills - able to apply food production (PR) technological processes (TP) and product conformity assessment methods is able to evaluate, substantiate and select the required level of TP automation and reasonably select the components of food production technological processes, optimal operating modes, compile, connect and experimentally test automation and electric drive circuits, perform calculations and evaluate process quality - laboratory work.

Competence - selection of the principle and optimal modes of automated process and equipment management, evaluation of performance quality and justification of improvement solutions - developed and defended independent work, test.

Requirements for awarding credit points

Theoretical test consists of three questions:
1. The question of automation theory;
2. The question of practical work.
3. The question of the working principle of operation of a given automation scheme.
The student is admitted to the test only if the laboratory works has been worked out, control tests №1 and №2 is approved and independent work is accepted.

Description of the organization and tasks of students’ independent work

The student prepares a report (10-15 pages) or a presentation in the amount of 8-12 slides on a freely chosen topic of food technology automation, including in independent work management schemes, diagrams and examples of engineering calculations. Independent work can be performed in the amount of 8-10 slides using computer programs EDrawMax, SCADA, TRACE MODE 6.

Criteria for Evaluating Learning Outcomes

The evaluation of the study course “test” is formed for each correct answer to the test question. The correct answer may be with slight imperfections or insignificant errors.
- Correct, comprehensive answer to each question: 3 points,
- Correct answer with minor deficiencies or errors: 2 points,
- Answer containing only basic concepts without explanation or with material errors: 1 point,
- No answer, wrong answer, very serious material errors in the answer: 0 points.
Obtaining 5 points out of 9, the student receives a course evaluation "test".
