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 course objective is to enable students to understand the working principles of the cybernetic systems that utilize information processing and feedback or feedforward control to automate both purely technical devices used in medical technology and systems that include the patient as part of the control loop. At the same time, graduates of the course will be able to use software for computer-aided design and simulation of cybernetic systems. Due to the complexity of this topic, the primary focus of this undergraduate course is on understanding the basic principles.
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.
