Prerequisites for registration:
Assesment methods:
 The evaluation is based on a point system. By fulfilling the study activities, students can acquire 100 points at maximum. A continuous assessment of student’s work and acquired knowledge is ensured via two laboratory assignments, 15 points each (30 points in total), and two written exams, also 15 points each (30 in total). The final exam is carried out in the form of an oral exam. Students can get a maximum of 40 points for the exam. The requirement for successful completion of the course is acquiring at least 56% of points for work during the semester (lab. assignments and written exams) and at least 56% of points for final exam. The overall grade is calculated using a standard FCFT grading scale.
Learning outcomes of the course unit:
By completing this course, the students have gained the knowledge about the components of automated control systems. Students know the types and operational principles of sensors and actuators, and can select particular sensor or actuator for specific application or physical conditions. Students master the use of programmable logic controllers and design of programs for control systems. Students also gained practical skills in electrical engineering for automation, including electrical wiring and configuration of sensors, actuators, PLCs, signal conversion and processing, and fault diagnostics.
Course contents:

The course is divided into three main parts. The first is dedicated to common types of sensing instruments and their principles of operation. Students will get acquainted with electric signals, characteristics of sensors, temperature sensors, pressure sensors, measurement of mechanics and physical properties of fluids, RC circuits, noise filters, and discrete input elements of automated systems. The second part is dedicated to actuators and drives. Students will learn about construction and operation principles of motors (DC and AC), motor control via power modulation, selection of motor for specific applications, and also about motorized actuators such as valves and pumps. The third part is dedicated to the basics of work with programmable logic controllers.
