Introduction to Feedback Control Systems: Concepts and Applications

This lecture introduces the fundamental concepts of feedback control systems, emphasizing their importance in various fields such as biology, economics, and engineering. The instructor discusses the principle of feedback, illustrating its presence in everyday systems like body temperature regulation, glucose control, and inflation management. The lecture outlines the components of feedback control systems, including the process, sensor, actuator, and controller, and provides examples of how these elements interact in biological and mechanical systems. The instructor also covers the course objectives, which include the analysis and synthesis of linear feedback control systems, and the teaching methods employed throughout the course. The lecture concludes with an overview of the course content, including modeling dynamic systems, analyzing system stability, and designing controllers. This foundational knowledge sets the stage for more advanced topics in subsequent lectures.
