Course description and aims

In cyber-physical systems (CPSs), one of the basic tasks is to automatically control physical systems connected by information communication technologies. In this lecture, we provide an introduction to the theory of feedback control. We start with reviewing the basics of Laplace transforms and then advance to understand analysis methods of feedback control systems. For the synthesis of control systems, we further study methods based on frequency responses. Later in the course, we introduce techniques in the discrete-time domain to learn implementation issues in digital control.

Student learning outcomes

To learn the basis of analysis and synthesis methods for control systems. In particular, the following issues will be emphasized:
- Advantages of feedback control
- Frequency responses
- Internal stability of feedback control systems
- Synthesis of feedback control systems: PID control, phase lead/lag compensators
- Introduction to digital control
- Matlab and its Control Systems Toolbox


Feedback control, dynamical systems, transfer functions, stability, frequency response, Bode diagram, controller synthesis, Digital control

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

This lecture will be given mostly in the lecture style. Participants will be given assignments, which need to be handed in by the specified dates.
