This course will introduce students to the fundamentals of dynamical systems and automatic control, focusing on the analysis and design of control systems using classical control theory. Emphasis is given on the controller design for single input-single output systems with applications to electrical, hydraulic, and mechanical systems.

1. Introduction to automatic control systems (history and applications)
2. Mathematical modelling of dynamical systems
a. Different types of systems, modelling (state-space description) and normalization
b. The presence of disturbancies and role of feedback, sensors and actuators
c. Examples: mechanical, thermal, hydraulic, electrical
d. Linearisation of non-linear systems
3. System Analysis: Time domain
a. System response for first and second order systems
b. Stability of linear systems
c. Controllability and observability
4. System Analysis: Frequency domain
a. Laplace transform Ι, transfer functions, analytical solution
b. Laplace transform ΙΙ, poles and zeros, BIBO stability
c. Frequency response: Bode and Nyquist diagrams
d. Stability: Bode and Nyquist criteria
e. Stability: Routh-Hurwitz algebraic criterion
f. Stability: Root-locus criterion
5. Feedback control systems
a. Closed-loop control – idea of feedback
b. Performance criteria
c. Specification of the desired closed-loop system behaviour
6. Controller design
a. Specifications
b. Controller design via root locus
c. P, PI, PD, PID controllers
d. Controller design of PID via “loop shaping”
e. Feedforward compensation, cascade control
