Mathematical Prerequisites
2-3 weeksBuild fluency in the mathematics underlying control theory: ordinary differential equations, linear algebra (eigenvalues, matrix operations), and the Laplace transform. These tools are essential for modeling and analyzing dynamical systems.

Modeling Dynamical Systems
2-3 weeksLearn to derive mathematical models of physical systems (mechanical, electrical, electromechanical) from first principles using Newton's laws, Kirchhoff's laws, and energy methods. Practice converting between differential equation, transfer function, and state-space representations.
Time-Domain Analysis
2-3 weeksAnalyze system behavior using step response, impulse response, and transient response characteristics. Study first- and second-order system dynamics, including rise time, settling time, overshoot, and steady-state error.
Stability Analysis
1-2 weeksMaster stability criteria including the Routh-Hurwitz criterion for algebraic stability testing, and develop intuition for how pole locations in the complex plane relate to stable, unstable, and marginally stable behavior.
Root Locus and Controller Design
2-3 weeksLearn the root locus method for visualizing how closed-loop poles move with gain. Design lead, lag, and PID compensators to meet transient and steady-state performance specifications.
Frequency-Domain Analysis and Design
2-3 weeksStudy frequency response methods including Bode plots, Nyquist diagrams, and the Nyquist stability criterion. Learn to assess gain margin, phase margin, and bandwidth, and design compensators in the frequency domain.
State-Space Methods and Modern Control
3-4 weeksTransition to modern control theory using state-space representations. Study controllability, observability, state feedback, pole placement, and observer design. Introduce the Linear-Quadratic Regulator and Kalman filter.
Advanced Topics and Applications
4-6 weeksExplore advanced areas such as nonlinear control and Lyapunov methods, robust control (H-infinity), adaptive control, digital control systems, and real-world applications in robotics, aerospace, and process control.
