Educational Goals

The course covers subjects related to measurement devices and process control techniques in the food process industry. The course aims to achieve the following learning outcomes for students:

  • Recognition of the necessity for measurements and control of processes in industry.
  • Acquisition of knowledge on industrial sensors and transducers.
  • Recognition of the dynamic character of phenomena/processes and the methods for its mathematical description.
  • Acquisition of knowledge for automatic process control systems and corresponding mathematical formulations aiming at the manipulation of the dynamic behavior of systems.
  • Familiarization on the control systems used in industry and acquisition of practical skills on their use.

General Skills

  • Analysis, interpretation and synthesis of information collected in scientific bibliography using information and communication technology.
  • Understanding of the need for action in dynamic conditions.
  • Comparative and multi-criteria analysis of proposed solutions.
  • Working in an interdisciplinary environment.
  • Autonomous work.
  • Decision making.
