Foundations of Linear Systems Theory

Understanding how dynamic systems behave is essential for modern engineering, robotics, and control systems. This course offers a clear, structured path to mastering the mathematical foundations of linear systems. By reading through this comprehensive text-focused course, you will transition from basic algebra to confidently analyzing complex multi-input multi-output systems. You will learn to build state-space models, evaluate system stability, and understand how to control and observe dynamic processes using modern analytical techniques. What you'll learn: - Understand the core mathematical principles of linear vector spaces and state-space representations. - Solve linear state equations for both continuous-time and discrete-time systems. - Analyze system stability using Lyapunov methods and eigenstructure assignment. - Evaluate controllability and observability to determine if a system can be guided to a desired state. - Apply modern state-feedback controller and observer design techniques. - Practice system analysis concepts through written step-by-step mathematical exercises. The course begins with foundational definitions of linearity and state variables before advancing to state transition matrices, stability criteria, and controller design. Each concept is paired with detailed written derivations and practical calculation exercises to solidify your understanding. This course is designed for beginners in control theory, engineering students, and self-taught developers looking to understand physical system modeling. No advanced prerequisites are required, though a basic familiarity with linear algebra and calculus is helpful.
