Laplace transform and transfer function. Bode and Nyquist plot. Basic dynamic elements. Control loop and its characteristics. Control loop stability and methods of stability analysis. Performance indices in time and frequency domain. Basic controller types. Control loop synthesis. Fixed set-point control and servo control. Control loop behaviour in regard to reference variable and disturbance. Classic methods of synthesis of linear continuous control systems. Synthesis in time and frequency domain. Empirical rules for setting the controller parameters. Improvement of dynamic properties of control systems by introducing feedforward and cascade control. Practical examples.

Knowledge and skills acquired

This course gives the basics of description of system dynamic behaviour, structural presentation of basic elements and systems of automatic control, feedback phenomenon in the system, and feedback system stability analysis. In addition to that, students acquire basic knowledge of control algorithm design and evaluation of the achieved control quality. Laboratory practice provides skills pertaining to use of basic software tools for control system analysis and synthesis (Matlab), as well as methodology of practical control system implementation.

Examination methods

Written and oral exam.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. build a mathematical model of a simple dynamic system

2. analyse dynamic behaviour of a system in a time area, complex variable area and frequency area

3. test a regulation circuit and analyse its static properties

4. test the stability of a control loop by applying analytical and graph-analytical methods

5. design a simple controller using grapho-analytical and synthesis methods

6. carry out an analysis of a control loop using Matlab

7. explain the structure and implementation of a digital control system
