Acquired competences:
Knowledge:

Students will aquire competencies in the field of basics of system theory. They are able to analyse systems in the time-, frequency- and Laplace-domain. They are getting experience in control system design criteria and practical knowledge how can be these criteria satisfied by standard design staregies. Students are able to design and analyze P, PI, PD and PID loops.

Skills:

The student is familiar with the technical terms related to control engineering. The student is capable of analyzing control systems based on fundamental principles. They are able to independently acquire deeper knowledge based on the basic knowledge obtained, to process the literature, and then to relate to the area.

Attitude:

Open to learning about and accepting ongoing professional and technological developments and innovations in the technical field, and reliably conveying them. Strives to make self-education one of the tools for achieving professional goals. In complex or unexpected decision-making situations, makes decisions while fully considering laws and ethical standards.

Autonomy and responsibilities:

Identifies the shortcomings of applied technologies, the risks of processes, and initiates actions to mitigate these. Monitors legislative, technical, technological, and administrative changes related to the field.
