Overview of Control Systems Engineering
Control systems engineering is a multidisciplinary field that focuses on the behavior of dynamic systems. It involves designing controllers that manage the behavior of these systems to achieve desired outputs. The primary goal is to ensure stability, performance, and efficiency in a variety of applications, from industrial automation to aerospace engineering.
Key Concepts in Control Systems
To fully grasp the content of "Control Systems Engineering," it’s essential to understand some fundamental concepts:
1. System Dynamics: The study of how systems change over time, often represented using differential equations.
