Course syllabus 1. Concept and history of cybernetics; fundamental laws of cybernetics (feedback, model, information). 2. Systems: technical and biological systems. Distinction between object, system, and model. Information processing in a control loop, structure of a feedback control loop, and examples of feedback loops in biomedical applications. 3. Input-output description of continuous linear systems. Differential equations, transfer functions in the Laplace and frequency domains, and time-domain characteristics. 4. Basic types of linear dynamic systems and their behavior in the time and frequency domains. First-order systems, higher-order systems, integrating systems. 5. State-space representation of systems; relationship between input-output and state-space descriptions. 6. Stability. Definition of stability, stability analysis of linear systems, stability criteria, transport delay and its effect on system stability. 7. Principles of feedback control. Stability of a closed-loop control system, feedforward control. 8. PID controllers. Their properties and tuning methods, as well as modifications of PID controllers. 9. Implementation of PID controllers using digital computers. Brief overview of control systems in medical technology. 10-11. Actuators and their control characteristics.

Learning outcomes
|
The objective of this course is to introduce students into the field of cybernetics with main emphasis on systems and control theory. Students will acquire the knowledge that will enable them to understand control systems used in medical instrumentation. Further they will gain a more general view of the feedback control as a principle that plays a crucial role in living organisms. In this way, students should be able to use systems and control theory as a tool for understanding many processes in living organisms and especially in human body.
Graduates of this course will understand the principles on which systems based on cybernetic methods are built, including those used to automate technical devices as well as systems that incorporate the patient as part of the control loop. This understanding will enable them to comprehend specific biomedical applications of these principles, whether encountered in advanced courses or master's-level studies, or in clinical practice.
