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